+
+  // == Enforcing Options ===============================================
+  //
+  // These options tell JSHint to be more strict towards your code. Use
+  // them if you want to allow only a safe subset of JavaScript, very
+  // useful when your codebase is shared with a big number of developers
+  // with different skill levels.
+
+  "curly"         : true,     // Require {} for every new block or scope.
+  "eqeqeq"        : true,     // Require triple equals i.e. `===`.
+  "forin"         : true,     // Require `for in` loops with `hasOwnPrototype`.
+  "immed"         : true,     // Require immediate invocations to be wrapped in parens e.g. `( function(){}() );`
+  "latedef"       : true,     // Prohibit variable use before definition.
+  "newcap"        : true,     // Require capitalization of all constructor functions e.g. `new F()`.

+  "nonew"         : true,     // Prohibit use of constructors for side-effects.
+  "regexp"        : true,     // Prohibit `.` and `[^...]` in regular expressions.
+  "undef"         : true,     // Require all non-global variables be declared before they are used.
+  "unused"        : true,     // Warn when variables are created but not used.
+  "trailing"      : true,     // Prohibit trailing whitespaces.
+  "es3"           : false,     // Prohibit trailing commas for old IE 
+  "esnext"        : true,     // Allow ES.next specific features such as `const` and `let`.
+
+  // == Relaxing Options ================================================
+  //
+  // These options allow you to suppress certain types of warnings. Use
+  // them only if you are absolutely positive that you know what you are
+  // doing.
+
+  "bitwise"       : false,    // Prohibit bitwise operators (&, |, ^, etc.).
+  "plusplus"      : false,    // Prohibit use of `++` & `--`.
+  "strict"        : false,    // Require `use strict` pragma in every file.
+  "asi"           : false,    // Tolerate Automatic Semicolon Insertion (no semicolons).
+  "boss"          : false,    // Tolerate assignments inside if, for & while. Usually conditions & loops are for comparison, not assignments.
+  "debug"         : false,    // Allow debugger statements e.g. browser breakpoints.
+  "eqnull"        : false,    // Tolerate use of `== null`.
+  "es5"           : false,    // Allow EcmaScript 5 syntax.
+  "evil"          : false,    // Tolerate use of `eval`.
+  "expr"          : false,    // Tolerate `ExpressionStatement` as Programs.
+  "funcscope"     : false,    // Tolerate declarations of variables inside of control structures while accessing them later from the outside.
+  "globalstrict"  : false,    // Allow global "use strict" (also enables 'strict').
+  "iterator"      : false,    // Allow usage of __iterator__ property.
+  "lastsemic"     : false,    // Tolerat missing semicolons when the it is omitted for the last statement in a one-line block.
+  "laxbreak"      : false,    // Tolerate unsafe line breaks e.g. `return [\n] x` without semicolons.
+  "laxcomma"      : false,    // Suppress warnings about comma-first coding style.

+  "onecase"       : false,    // Tolerate switches with just one case.
+  "proto"         : false,    // Tolerate __proto__ property. This property is deprecated.

+  "scripturl"     : false,    // Tolerate script-targeted URLs.
+  "smarttabs"     : false,    // Tolerate mixed tabs and spaces when the latter are used for alignmnent only.
+  "shadow"        : false,    // Allows re-define variables later in code e.g. `var x=1; x=2;`.
+  "sub"           : false,    // Tolerate all forms of subscript notation besides dot notation e.g. `dict['key']` instead of `dict.key`.
+  "supernew"      : false,    // Tolerate `new function () { ... };` and `new Object;`.
+  "validthis"     : false,    // Tolerate strict violations when the code is running in strict mode and you use this in a non-constructor function.
+
+  // == Environments ====================================================
+  //
+  // These options pre-define global variables that are exposed by
+  // popular JavaScript libraries and runtime environments—such as
+  // browser or node.js.
+
+  "browser"       : true,     // Standard browser globals e.g. `window`, `document`.
+  "devel"         : false,    // Allow development statements e.g. `console.log();`.
+  "jquery"        : false,    // Enable globals exposed by jQuery JavaScript library.
+  "node"          : false,    // Enable globals available when code is running inside of the NodeJS runtime environment.
+

+  // not be improved in any way and might be removed at any point.

+  // == Global Variables ====================================================
+  //
+  // These options pre-define global variables specific 
+  // to your app that hang off `window`.
+
+  "predef": [
+    "define" // amd loader
