Types

Primitives: When you access a primitive type you work directly on its value
- string
- number
- boolean
- null
- undefined
```
var foo = 1,
    bar = foo;

bar = 9;

console.log(foo, bar); // => 1, 9
```

Complex: When you access a complex type you work on a reference to its value

object
array
function

var foo = [1, 2],
    bar = foo;

bar[0] = 9;

console.log(foo[0], bar[0]); // => 9, 9

[⬆]

undefined

undefined is an object. You should use it as an object. You can test for it. For instance:

// good
function pow(a, b) {
  if (b === undefined) {
    b = 1;
  }
  return Math.pow(a, b);
}

// bad
function pow(a, b) {
  if (typeof b == "undefined") {
    b = 1;
  }
  return Math.pow(a, b);
}

Only use typeof x == "undefined" when the variable (x) may not be declared, and it would be an error to test x === undefined:
```
if (typeof Module == "undefined") {
  Module = {};
}

// But also okay, for browser-only code:
if (window.Module === undefined) {
  Module = {};
}
```
Note that you can't use window in Node.js; if you think your code could be used in a server context you should use the first form.

Objects

Use the literal syntax for object creation.

// bad
var item = new Object();

// good
var item = {};

You may use reserved words as keys.

As an example that reserved words are both okay right now and will be indefinitely, the IndexedDB API uses cursor.continue()

[⬆]

Arrays

Use the literal syntax for array creation

// bad
var items = new Array();

// good
var items = [];

If you don't know array length use Array#push.

var someStack = [];


// bad
someStack[someStack.length] = 'abracadabra';

// good
someStack.push('abracadabra');

When you need to copy an array use Array#slice. jsPerf

var len = items.length,
    itemsCopy = [],
    i;

// bad
for (i = 0; i < len; i++) {
  itemsCopy[i] = items[i];
}

// good
itemsCopy = Array.prototype.slice.call(items);

If you want to use the value of arguments anywhere, as a list, turn it into a real Array using Array#slice.

function applyall(func) {
  var rest = Array.prototype.slice.call(arguments, 1);
  rest.map(func);
}

[⬆]

Strings

Use single or double quotes (' or ") for strings. There is a slight preference for double-quotes, aligning with Mozilla style.
Strings longer than 80 characters should be written across multiple lines using string concatenation. (FIXME: I can't decide how much I care)

Note: If overused, long strings with concatenation could impact performance. jsPerf & Discussion

// bad
var errorMessage = 'This is a super long error that was thrown because of Batman. When you stop to think about how Batman had anything to do with this, you would get nowhere fast.';

// bad
var errorMessage = 'This is a super long error that \
was thrown because of Batman. \
When you stop to think about \
how Batman had anything to do \
with this, you would get nowhere \
fast.';


// good
var errorMessage = 'This is a super long error that ' +
  'was thrown because of Batman.' +
  'When you stop to think about ' +
  'how Batman had anything to do ' +
  'with this, you would get nowhere ' +
  'fast.';

When programatically building up a string, use Array#join instead of string concatenation. Mostly for IE: jsPerf.

var items,
    messages,
    length, i;

messages = [{
    state: 'success',
    message: 'This one worked.'
},{
    state: 'success',
    message: 'This one worked as well.'
},{
    state: 'error',
    message: 'This one did not work.'
}];

length = messages.length;

// bad
function inbox(messages) {
  items = '<ul>';

  for (i = 0; i < length; i++) {
    items += '<li>' + messages[i].message + '</li>';
  }

  return items + '</ul>';
}

// good
function inbox(messages) {
  items = [];

  for (i = 0; i < length; i++) {
    items[i] = messages[i].message;
  }

  return '<ul><li>' + items.join('</li><li>') + '</li></ul>';
}

[⬆]

Functions

Function expressions:

// anonymous function expression
var anonymous = function () {
  return true;
};

// named function expression
var named = function named() {
  return true;
};

// immediately-invoked function expression (IIFE)
(function () {
  console.log('Welcome to the Internet. Please follow me.');
})();

Never declare a function in a non-function block (if, while, etc). Assign the function to a variable instead. Browsers will allow you to do it, but they all interpret it differently, which is bad news bears.

Note: ECMA-262 defines a block as a list of statements. A function declaration is not a statement. Read ECMA-262's note on this issue.

// bad
if (currentUser) {
  function test() {
    console.log('Nope.');
  }
}

// good
if (currentUser) {
  var test = function test() {
    console.log('Yup.');
  };
}

Never name a parameter arguments, this will take precedence over the arguments object that is given to every function scope.

// bad
function nope(name, options, arguments) {
  // ...stuff...
}

// good
function yup(name, options, args) {
  // ...stuff...
}

[⬆]

Properties

Use dot notation when accessing properties.

var luke = {
  jedi: true,
  age: 28
};

// bad
var isJedi = luke['jedi'];

// good
var isJedi = luke.jedi;

Use subscript notation [] when accessing properties with a variable.

var luke = {
  jedi: true,
  age: 28
};

function getProp(prop) {
  return luke[prop];
}

var isJedi = getProp('jedi');

Also use subscript notation when accessing a property that is not a valid identifier.
```
var preferredName = props['preferred-name'];
```
[⬆]

Variables

Always use var to declare variables. Not doing so will result in global variables. We want to avoid polluting the global namespace. Captain Planet warned us of that.
```
// bad
superPower = new SuperPower();

// good
var superPower = new SuperPower();
```

Use a separate var declaration for each variable. This allows variable declarations to be individually reordered or deleted.

// good
var items = getItems();
var goSportsTeam = true;
var dragonball = 'z';

// bad
var items = getItems(),
    goSportsTeam = true,
    dragonball = 'z';

Assign variables at the top of their scope. This helps avoid issues with variable declaration and assignment hoisting related issues.

// bad
function() {
  test();
  console.log('doing stuff..');

  //..other stuff..

  var name = getName();

  if (name === 'test') {
    return false;
  }

  return name;
}

// good
function() {
  var name = getName();

  test();
  console.log('doing stuff..');

  //..other stuff..

  if (name === 'test') {
    return false;
  }

  return name;
}

// bad
function() {
  var name = getName();

  if (!arguments.length) {
    return false;
  }

  return true;
}

// good
function() {
  if (!arguments.length) {
    return false;
  }

  var name = getName();

  return true;
}

As an exception, declaring a variable in a for loop is common and okay.
```
// ok
for (var i=0; i<array.length; i++) {...}
```
[⬆]

Hoisting

Variable declarations get hoisted to the top of their scope, their assignment does not.

// we know this wouldn't work (assuming there
// is no notDefined global variable)
function example() {
  console.log(notDefined); // => throws a ReferenceError
}

// creating a variable declaration after you
// reference the variable will work due to
// variable hoisting. Note: the assignment
// value of `true` is not hoisted.
function example() {
  console.log(declaredButNotAssigned); // => undefined
  var declaredButNotAssigned = true;
}

// The interpreter is hoisting the variable
// declaration to the top of the scope.
// Which means our example could be rewritten as:
function example() {
  var declaredButNotAssigned;
  console.log(declaredButNotAssigned); // => undefined
  declaredButNotAssigned = true;
}

Anonymous function expressions hoist their variable name, but not the function assignment.

function example() {
  console.log(anonymous); // => undefined

  anonymous(); // => TypeError anonymous is not a function

  var anonymous = function() {
    console.log('anonymous function expression');
  };
}

Named function expressions hoist the variable name, not the function name or the function body.

function example() {
  console.log(named); // => undefined

  named(); // => TypeError named is not a function

  superPower(); // => ReferenceError superPower is not defined

  var named = function superPower() {
    console.log('Flying');
  };


  // the same is true when the function name
  // is the same as the variable name.
  function example() {
    console.log(named); // => undefined

    named(); // => TypeError named is not a function

    var named = function named() {
      console.log('named');
    };
  }
}

Function declarations hoist their name and the function body.

function example() {
  superPower(); // => Flying

  function superPower() {
    console.log('Flying');
  }
}

Conditional Expressions & Equality

Use === and !== over == and !=. This is not a hard requirement, except when comparing something specifically against 0, null or undefined. (The Mozilla guide specifically discourages ===, so I'm landing somewhere in between.)
Conditional expressions are evaluated using coercion with the ToBoolean method and always follow these simple rules:
- Objects evaluate to true
- Undefined evaluates to false
- Null evaluates to false
- Booleans evaluate to the value of the boolean
- Numbers evalute to false if +0, -0, or NaN, otherwise true
- Strings evaluate to false if an empty string '', otherwise true
```
if ([0]) {
  // true
  // An array is an object, objects evaluate to true
}
```

Use shortcuts.

// bad
if (name !== '') {
  // ...stuff...
}

// good
if (name) {
  // ...stuff...
}

// bad
if (collection.length > 0) {
  // ...stuff...
}

// good
if (collection.length) {
  // ...stuff...
}

For more information see Truth Equality and JavaScript by Angus Croll

[⬆]

Blocks

Use braces with all blocks.

// bad
if (test)
  return false;

// bad
if (test) return false;

// good
if (test) {
  return false;
}

// usually bad (sometimes fine, like in a call to Array#filter)
function () { return false; }

// good
function() {
  return false;
}

[⬆]

Comments

Use /** ... */ for multiline comments, especially documentation. Include a description, specify types and values for all parameters and return values. For commentary or FIXMEs this is less of a concern.

// bad
// make() returns a new element
// based on the passed in tag name
//
// @param <String> tag
// @return <Element> element
function make(tag) {

  // ...stuff...

  return element;
}

// good FIXME: not sure if I care about leading *'s
/**
 * make() returns a new element
 * based on the passed in tag name
 *
 * @param <String> tag
 * @return <Element> element
 */
function make(tag) {

  // ...stuff...

  return element;
}

Use // for single line comments. Place single line comments on a newline above the subject of the comment. End a comment in : to make it clear what the subject of the comment is.

// bad
var active = true;  // is current tab

// good
// is current tab
var active = true;

// bad
function getType() {
  console.log('fetching type...');
  // set the default type to 'no type'
  var type = this._type || 'no type';
  return type;
}

// good
function getType() {
  console.log('fetching type...');
  // set the default type to 'no type':
  var type = this._type || 'no type';
  return type;
}

[⬆]

Use // FIXME ... liberally. Sometimes you are focused on one thing while coding, and want to avoid getting distracted by another issue, but you sense the issue exists: it is better to put in a FIXME note than to leave it forgotten. But do try to delete obsolete FIXMEs.

Whitespace

Use soft tabs set to 2 spaces

// bad
function() {
∙∙∙∙var name;
}

// bad
function() {
∙var name;
}

// good
function() {
∙∙var name;
}

Place 1 space before the leading brace.

// bad
function test(){
  console.log('test');
}

// good
function test() {
  console.log('test');
}

// bad
dog.set('attr',{
  age: '1 year',
  breed: 'Bernese Mountain Dog'
});

// good
dog.set('attr', {
  age: '1 year',
  breed: 'Bernese Mountain Dog'
});

Place an empty newline at the end of the file.

// bad
(function(global) {
  // ...stuff...
})(this);

// good
(function(global) {
  // ...stuff...
})(this);

Use indentation when making long method chains.

// bad
$('#items').find('.selected').highlight().end().find('.open').updateCount();

// good
$('#items')
  .find('.selected')
    .highlight()
    .end()
  .find('.open')
    .updateCount();

// bad
var leds = stage.selectAll('.led').data(data).enter().append("svg:svg").class('led', true)
    .attr('width',  (radius + margin) * 2).append("svg:g")
    .attr("transform", "translate(" + (radius + margin) + "," + (radius + margin) + ")")
    .call(tron.led);

// good
var leds = stage.selectAll('.led')
    .data(data)
  .enter().append("svg:svg")
    .class('led', true)
    .attr('width',  (radius + margin) * 2)
  .append("svg:g")
    .attr("transform", "translate(" + (radius + margin) + "," + (radius + margin) + ")")
    .call(tron.led);

Always put a space after function (you wouldn't do while(x) {...}, would you?)

// bad
el.addEventListener(function() {...});

// good
el.addEventListener(function () {...});

[⬆]

Leading Commas

Nope.

// bad
var once
  , upon
  , aTime;

// good
var once,
    upon,
    aTime;

// bad
var hero = {
    firstName: 'Bob'
  , lastName: 'Parr'
  , heroName: 'Mr. Incredible'
  , superPower: 'strength'
};

// good
var hero = {
  firstName: 'Bob',
  lastName: 'Parr',
  heroName: 'Mr. Incredible',
  superPower: 'strength'
};

[⬆]

Semicolons

Yup.

// bad
(function() {
  var name = 'Skywalker'
  return name
})()

// good
(function() {
  var name = 'Skywalker';
  return name;
})();

// good
;(function() {
  var name = 'Skywalker';
  return name;
})();

[⬆]

Type Casting & Coercion

Perform type coercion at the beginning of the statement.

Strings:

//  => this.reviewScore = 9;

// bad FIXME: not sure why this is bad
var totalScore = this.reviewScore + '';

// good
var totalScore = '' + this.reviewScore;

// bad
var totalScore = '' + this.reviewScore + ' total score';

// good
var totalScore = this.reviewScore + ' total score';

Use parseInt for Numbers and always with a radix for type casting, like parseInt(x, 10), never parseInt(x).

If for whatever reason you are doing something wild and parseInt is your bottleneck and need to use Bitshift for performance reasons, leave a comment explaining why and what you're doing.

var inputValue = '4';

// bad
var val = new Number(inputValue);

// bad
var val = +inputValue;

// bad
var val = inputValue >> 0;

// bad
var val = parseInt(inputValue);

// good
var val = Number(inputValue);

// good
var val = parseInt(inputValue, 10);

// good
/**
 * parseInt was the reason my code was slow.
 * Bitshifting the String to coerce it to a
 * Number made it a lot faster.
 */
var val = inputValue >> 0;

Booleans:

var age = 0;

// bad
var hasAge = new Boolean(age);

// iffy
var hasAge = Boolean(age);

// good
var hasAge = !!age;

[⬆]

Naming Conventions

Avoid single letter names. Be descriptive with your naming.

// bad
function q() {
  // ...stuff...
}

// good
function query() {
  // ..stuff..
}

Use camelCase when naming objects, functions, and instances

// bad
var OBJEcttsssss = {};
var this_is_my_object = {};
// so bad it's just silly
var this-is-my-object = {};
function c() {};
var u = new user({
  name: 'Bob Parr'
});

// good
var thisIsMyObject = {};
function thisIsMyFunction() {};
var user = new User({
  name: 'Bob Parr'
});

Use PascalCase when naming constructors or classes

// bad
function user(options) {
  this.name = options.name;
}

var bad = new user({
  name: 'nope'
});

// good
function User(options) {
  this.name = options.name;
}

var good = new User({
  name: 'yup'
});

Use a leading underscore _ when naming private properties

// bad
this.__firstName__ = 'Panda';
this.firstName_ = 'Panda';

// good
this._firstName = 'Panda';

When saving a reference to this use _this or self FIXME: only _this?

// ok?
function() {
  var self = this;
  return function() {
    console.log(self);
  };
}

// bad
function() {
  var that = this;
  return function() {
    console.log(that);
  };
}

// good
function() {
  var _this = this;
  return function() {
    console.log(_this);
  };
}

Name your functions. This is helpful for stack traces. FIXME: I don't know if it really matters. In the browser stack traces give line numbers, the name isn't that big of a deal.
```
// bad
var log = function(msg) {
  console.log(msg);
};

// good
var log = function log(msg) {
  console.log(msg);
};
```

Name your functions if they are self-recursive.

$.ajax({
  success: function success(result) {
    if (Array.isArray(result)) {
      result.forEach(function (item) {
        success(item);
      });
    }
    // normal behavior...
  }
});

[⬆]

Accessors

Accessor functions for properties are not required

If you do make accessor functions use getVal() and setVal('hello')

// bad
dragon.age();

// good
dragon.getAge();

// bad
dragon.age(25);

// good
dragon.setAge(25);

If the property is a boolean, use isVal() or hasVal()

// bad
if (!dragon.age()) {
  return false;
}

// good
if (!dragon.hasAge()) {
  return false;
}

It's okay to create get() and set() functions, but be consistent.

function Jedi(options) {
  options || (options = {});
  var lightsaber = options.lightsaber || 'blue';
  this.set('lightsaber', lightsaber);
}

Jedi.prototype.set = function(key, val) {
  this[key] = val;
};

Jedi.prototype.get = function(key) {
  return this[key];
};

[⬆]

Constructors

Prefer Object.create over the new operator.

var MyClass = function () {
  var obj = Object.create(Class.prototype);
  obj.constructor.apply(obj, arguments);
  return obj;
};
MyClass.prototype = {...};

This is essentially equivalent to what new does, but is less error-prone (you can't call it incorrectly), and easier to work with when defining different object layouts. I prefer this class pattern:

function Class(super, properties) {
  // The case when there is no superclass:
  var prototype = super;
  // Otherwise:
  if (properties) {
    prototype = Object.create(super);
    for (var a in properties) {
      if (properties.hasOwnProperty(a)) {
        prototype[a] = properties[a];
      }
    }
  }
  return function () {
    var obj = Objet.create(prototype);
    obj.constructor.apply(this, arguments);
    return obj;
  };
}

MyClass = Class({
  constructor: function (...) {...}
});

Methods can return this to help with method chaining. Or not, whatever.

// bad (the return is pointless!)
Jedi.prototype.jump = function() {
  this.jumping = true;
  return true;
};

// fine
Jedi.prototype.setHeight = function(height) {
  this.height = height;
};

var luke = new Jedi();
luke.jump(); // => true
luke.setHeight(20) // => undefined

// maybe better
Jedi.prototype.jump = function() {
  this.jumping = true;
  return this;
};

Jedi.prototype.setHeight = function(height) {
  this.height = height;
  return this;
};

var luke = new Jedi();

luke.jump()
  .setHeight(20);

It's okay to write a custom toString() method, just make sure it works successfully and causes no side effects.

function Jedi(options) {
  options || (options = {});
  this.name = options.name || 'no name';
}

Jedi.prototype.getName = function getName() {
  return this.name;
};

Jedi.prototype.toString = function toString() {
  return 'Jedi - ' + this.getName();
};

You may also wish to write a .toSource() method, which is a rough convention for a "programmer friendly" representation of the object.

[⬆]

JSHint

The code should be clean with JSHint.
JSHint is kind of tedious about variable declarations. It doesn't like this, for instance:
```
try {
  var foo = bar();
} catch (e) {
  throw 'Foo';
}
foo.method();
```
JSHint doesn't like this, it will claim that foo is used out of scope. This is silly, but we fix it anyway just to get JSHint off our backs.

.jshintrc can have these options (consider this a suggestion, more than a requirement):

{
  "curly": true,
  "noarg": true,
  "bitwise": true,
  "es5": true
}

Modules

The file should be named with camelCase, and match the name of the single export (if not using a loader like require.js).
Add a method called noConflict() that sets the exported module to the previous version and returns this one.

Always declare 'use strict'; at the top of the module.

// fancyInput/fancyInput.js

!function(global) {
  'use strict';

  var previousFancyInput = global.FancyInput;

  function FancyInput(options) {
    this.options = options || {};
  }

  FancyInput.noConflict = function noConflict() {
    global.FancyInput = previousFancyInput;
    return FancyInput;
  };

  global.FancyInput = FancyInput;
}(this);

Alternately when using requirejs or generally AMD-style modules, define your module like so:
```
// in myModule.js
define(["prereq"], function (prereq) {
  var myModule = {};
  myModule.foo = ...
  return myModule;
});
```
That is, create a single object that you return, which is named after the module. Then myModule.foo will go by exactly that name in all locations, including where it is used and defined.

Do not include the name of the module in the define() call.

Sometimes you need to create a module-system-neutral module. There are two approaches, depending on whether you have dependencies. No dependencies:

(function () {
var myLibrary = {...};

if (typeof define != "undefined") {
  // You can probably determine this statically:
  if (typeof myLibrary == "function") {
    define([], function () {return myLibrary;});
  } else {
    define([], myLibrary});
  }
} else {
  window.myLibrary = myLibrary;
}

})();

Or if you have dependencies:

(function () {
function init($) {
  return {my library object};
}
if (typeof define != "undefined") {
  define(["jquery"], init);
} else {
  window.myLibrary = init(jQuery);
}
})();

[⬆]

jQuery

Prefix jQuery object variables with a $. FIXME: can't decide if I care

// bad
var sidebar = $('.sidebar');

// good
var $sidebar = $('.sidebar');

Cache jQuery lookups.

// bad
function setSidebar() {
  $('.sidebar').hide();

  // ...stuff...

  $('.sidebar').css({
    'background-color': 'pink'
  });
}

// good
function setSidebar() {
  var $sidebar = $('.sidebar');
  $sidebar.hide();

  // ...stuff...

  $sidebar.css({
    'background-color': 'pink'
  });
}

For DOM queries use Cascading $('.sidebar ul') or parent > child $('.sidebar > .ul'). jsPerf

Use find with scoped jQuery object queries.

// bad
$('.sidebar', 'ul').hide();

// bad
$('.sidebar').find('ul').hide();

// good
$('.sidebar ul').hide();

// good
$('.sidebar > ul').hide();

// good (slower)
$sidebar.find('ul');

// good (faster)
$($sidebar[0]).find('ul');
