  // == Enforcing Options ===============================================
  //
  // These options tell JSHint to be more strict towards your code.

  "bitwise"       : false,     // Prohibit bitwise operators (&, |, ^, etc.).
  "camelcase"     : true,     // Force all variable names to use either camelCase style or UPPER_CASE with underscores.
  "curly"         : true,     // Require {} for every new block or scope.
  "eqeqeq"        : true,     // Require triple equals i.e. `===`.

  "forin"         : true,     // Tolerate `for in` loops without `hasOwnPrototype`.

  "indent"        : 4,        // Specify indentation spacing
  "latedef"       : "nofunc", // Prohibit variable use before definition (functions ok).
  "newcap"        : true,     // Require capitalization of all constructor functions e.g. `new F()`.
  "noarg"         : true,     // Prohibit use of `arguments.caller` and `arguments.callee`.
  "noempty"       : true,     // Prohibit use of empty blocks.

  "undef"         : true,     // Require all non-global variables be declared before they are used.
  "unused"        : true,     // Prevent declaring unused functions and variables.
  "strict"        : true,     // Require `use strict` pragma in every file.
  "maxparams"     : 4,        // Set the max number of formal parameters allowed per function
  "maxlen"        : 120,      // Set the maximum line length

  // == 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.

  "asi"           : false,    // Tolerate Automatic Semicolon Insertion (no semicolons).
  "boss"          : false,    // Tolerate assignments inside if, for & while. Usually conditions & loops are for comparison, not assignments.

  "eqnull"        : false,    // Tolerate use of `== null`.
  "esnext"        : false,    // Allow ES.next specific features such as `const` and `let`.

  "expr"          : false,    // Tolerate `ExpressionStatement` as Programs.
  "funcscope"     : false,    // Tolerate declarations of variables inside of control structures while accessing them later from the outside.

  "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.
  "loopfunc"      : false,    // Allow functions to be defined within loops.
  "moz"           : false,    // Use Mozilla JavaScript extensions. Unless you develop specifically for the Firefox web browser you don't need this option.
  "multistr"      : false,    // Tolerate multi-line strings.
  "proto"         : false,    // Tolerate __proto__ property. This property is deprecated.
  "scripturl"     : false,    // Tolerate script-targeted URLs.
  "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`.
  "couch"         : false,    // Enable globals exposed by CouchDB.
  "devel"         : false,    // Allow development statements e.g. `console.log();`.
  "jquery"        : false,    // Enable globals exposed by jQuery JavaScript library.
  "node"          : true,     // Enable globals available when code is running inside of the NodeJS runtime environment.
  "nonstandard"   : false,    // Define non-standard but widely adopted globals such as escape and unescape.
  "wsh"           : false,    // Enable globals available when your code is running as a script for the Windows Script Host.

  // == Global Variables ================================================
  //
  // These will be ignored by jsHint and will not throw warning caused by the
  // debug or undef options
