Below is a breakdown of the mapping used -to convert each method. - -#### Capped Iteratee Arguments - -Iteratee arguments are capped to avoid gotchas with variadic iteratees. -```js -// The `lodash/map` iteratee receives three arguments: -// (value, index|key, collection) -_.map(['6', '8', '10'], parseInt); -// ➜ [6, NaN, 2] - -// The `lodash/fp/map` iteratee is capped at one argument: -// (value) -fp.map(parseInt)(['6', '8', '10']); -// ➜ [6, 8, 10] -``` - -Methods that cap iteratees to one argument:
-<%= toFuncList(_.keys(_.pickBy(mapping.iterateeAry, _.partial(_.eq, _, 1)))) %> - -Methods that cap iteratees to two arguments:
-<%= toFuncList(_.keys(_.pickBy(mapping.iterateeAry, _.partial(_.eq, _, 2)))) %> - -The iteratee of `mapKeys` is capped to one argument: `(key)` - -#### Fixed Arity - -Methods have fixed arities to support auto-currying. -```js -// `lodash/padStart` accepts an optional `chars` param. -_.padStart('a', 3, '-') -// ➜ '--a' - -// `lodash/fp/padStart` does not. -fp.padStart(3)('a'); -// ➜ ' a' -fp.padCharsStart('-')(3)('a'); -// ➜ '--a' -``` - -Methods with a fixed arity of one:
-<%= toFuncList(_.difference(mapping.aryMethod[1], _.keys(mapping.skipFixed))) %> - -Methods with a fixed arity of two:
-<%= toFuncList(_.difference(mapping.aryMethod[2], _.keys(mapping.skipFixed))) %> - -Methods with a fixed arity of three:
-<%= toFuncList(_.difference(mapping.aryMethod[3], _.keys(mapping.skipFixed))) %> - -Methods with a fixed arity of four:
-<%= toFuncList(_.difference(mapping.aryMethod[4], _.keys(mapping.skipFixed))) %> - -#### Rearranged Arguments - -Method arguments are rearranged to make composition easier. -```js -// `lodash/filter` is data-first iteratee-last: -// (collection, iteratee) -var compact = _.partial(_.filter, _, Boolean); -compact(['a', null, 'c']); -// ➜ ['a', 'c'] - -// `lodash/fp/filter` is iteratee-first data-last: -// (iteratee, collection) -var compact = fp.filter(Boolean); -compact(['a', null, 'c']); -// ➜ ['a', 'c'] -``` - -##### Most methods follow these rules - -A fixed arity of two has an argument order of:
-<%= toArgOrder(mapping.aryRearg[2]) %> - -A fixed arity of three has an argument order of:
-<%= toArgOrder(mapping.aryRearg[3]) %> - -A fixed arity of four has an argument order of:
-<%= toArgOrder(mapping.aryRearg[4]) %> - -##### Exceptions to the rules - -Methods that accept an array as their last or only argument:
-<%= toFuncList(_.keys(mapping.methodSpread)) %> - -Methods with unchanged argument orders:
-<%= toFuncList(_.keys(mapping.skipRearg)) %> - -Methods with custom argument orders:
-<%= _.map(_.keys(mapping.methodRearg), methodName => { - const orders = mapping.methodRearg[methodName]; - return ' * `_.' + methodName + '` has an order of ' + toArgOrder(orders); -}).join('\n') %> - -The iteratee of `reduceRight` has an argument order of: `(b, a)` - -#### New Methods - -Not all variadic methods have corresponding new method variants. Feel free to -[request](https://github.com/lodash/lodash/blob/master/.github/CONTRIBUTING.md#feature-requests) -any additions. - -Methods created to accommodate Lodash’s variadic methods:
-<%= toFuncList(_.keys(mapping.remap)) %> - -#### Aliases - -There are <%= _.size(mapping.aliasToReal) %> method aliases:
-<%= _.map(_.keys(mapping.aliasToReal).sort(), alias => { - const realName = mapping.aliasToReal[alias]; - return ' * `_.' + alias + '` is an alias of `_.' + realName + '`'; -}).join('\n') %> - -## Placeholders - -The placeholder argument, which defaults to `_`, may be used to fill in method -arguments in a different order. Placeholders are filled by the first available -arguments of the curried returned function. -```js -// The equivalent of `2 > 5`. -_.gt(2)(5); -// ➜ false - -// The equivalent of `_.gt(5, 2)` or `5 > 2`. -_.gt(_, 2)(5); -// ➜ true -``` - -## Chaining - -The `lodash/fp` module **does not** convert chain sequence methods. See -[Izaak Schroeder’s article](https://medium.com/making-internets/why-using-chain-is-a-mistake-9bc1f80d51ba) -on using functional composition as an alternative to method chaining. - -## Convert - -Although `lodash/fp` & its method modules come pre-converted, there are times -when you may want to customize the conversion.

It can be a - function or an array of strings. - - space an optional parameter that specifies the indentation - of nested structures. If it is omitted, the text will - be packed without extra whitespace. If it is a number, - it will specify the number of spaces to indent at each - level. If it is a string (such as '\t' or ' '), - it contains the characters used to indent at each level. - - This method produces a JSON text from a JavaScript value. - - When an object value is found, if the object contains a toJSON - method, its toJSON method will be called and the result will be - stringified. A toJSON method does not serialize: it returns the - value represented by the name/value pair that should be serialized, - or undefined if nothing should be serialized. The toJSON method - will be passed the key associated with the value, and this will be - bound to the value - - For example, this would serialize Dates as ISO strings. - - Date.prototype.toJSON = function (key) { - function f(n) { - // Format integers to have at least two digits. - return n < 10 ? '0' + n : n; - } - - return this.getUTCFullYear() + '-' + - f(this.getUTCMonth() + 1) + '-' + - f(this.getUTCDate()) + 'T' + - f(this.getUTCHours()) + ':' + - f(this.getUTCMinutes()) + ':' + - f(this.getUTCSeconds()) + 'Z'; - }; - - You can provide an optional replacer method. It will be passed the - key and value of each member, with this bound to the containing - object. The value that is returned from your method will be - serialized. If your method returns undefined, then the member will - be excluded from the serialization. - - If the replacer parameter is an array of strings, then it will be - used to select the members to be serialized. It filters the results - such that only members with keys listed in the replacer array are - stringified. - - Values that do not have JSON representations, such as undefined or - functions, will not be serialized. Such values in objects will be - dropped; in arrays they will be replaced with null. You can use - a replacer function to replace those with JSON values. - JSON.stringify(undefined) returns undefined. - - The optional space parameter produces a stringification of the - value that is filled with line breaks and indentation to make it - easier to read. - - If the space parameter is a non-empty string, then that string will - be used for indentation. If the space parameter is a number, then - the indentation will be that many spaces. - - Example: - - text = JSON.stringify(['e', {pluribus: 'unum'}]); - // text is '["e",{"pluribus":"unum"}]' - - - text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t'); - // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]' - - text = JSON.stringify([new Date()], function (key, value) { - return this[key] instanceof Date ? - 'Date(' + this[key] + ')' : value; - }); - // text is '["Date(---current time---)"]' - - - JSON.parse(text, reviver) - This method parses a JSON text to produce an object or array. - It can throw a SyntaxError exception. - - The optional reviver parameter is a function that can filter and - transform the results. It receives each of the keys and values, - and its return value is used instead of the original value. - If it returns what it received, then the structure is not modified. - If it returns undefined then the member is deleted. - - Example: - - // Parse the text. Values that look like ISO date strings will - // be converted to Date objects. - - myData = JSON.parse(text, function (key, value) { - var a; - if (typeof value === 'string') { - a = -/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value); - if (a) { - return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4], - +a[5], +a[6])); - } - } - return value; - }); - - myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) { - var d; - if (typeof value === 'string' && - value.slice(0, 5) === 'Date(' && - value.slice(-1) === ')') { - d = new Date(value.slice(5, -1)); - if (d) { - return d; - } - } - return value; - }); - - - This is a reference implementation.
