|
22 // == Enforcing Options =============================================== |
|
23 // |
|
24 // These options tell JSHint to be more strict towards your code. Use |
|
25 // them if you want to allow only a safe subset of JavaScript, very |
|
26 // useful when your codebase is shared with a big number of developers |
|
27 // with different skill levels. |
|
28 |
|
29 "bitwise" : true, // Prohibit bitwise operators (&, |, ^, etc.). |
|
30 "curly" : true, // Require {} for every new block or scope. |
|
31 "eqeqeq" : true, // Require triple equals i.e. `===`. |
|
32 "forin" : true, // Tolerate `for in` loops without `hasOwnPrototype`. |
|
33 "immed" : true, // Require immediate invocations to be wrapped in parens e.g. `( function(){}() );` |
|

|
43 "trailing" : true, // Prohibit trailing whitespaces. |
|
44 |
|
45 // == Relaxing Options ================================================ |
|
46 // |
|
47 // These options allow you to suppress certain types of warnings. Use |
|
48 // them only if you are absolutely positive that you know what you are |
|
49 // doing. |
|
50 |
|
51 "asi" : false, // Tolerate Automatic Semicolon Insertion (no semicolons). |
|
52 "boss" : false, // Tolerate assignments inside if, for & while. Usually conditions & loops are for comparison, not assignments. |

|
59 "funcscope" : false, // Tolerate declarations of variables inside of control structures while accessing them later from the outside. |
|
60 "globalstrict" : false, // Allow global "use strict" (also enables 'strict'). |
|
61 "iterator" : false, // Allow usage of __iterator__ property. |
|
62 "lastsemic" : false, // Tolerat missing semicolons when the it is omitted for the last statement in a one-line block. |
|
63 "laxbreak" : false, // Tolerate unsafe line breaks e.g. `return [\n] x` without semicolons. |
|

77 // == Environments ==================================================== |
|
78 // |

79 // These options pre-define global variables that are exposed by |

80 // popular JavaScript libraries and runtime environments—such as |
|
81 // browser or node.js. |

|
106 // |
