JSHint configuration file Json Format

bitwise - Prohibit the use of bitwise operators (&, |, ^, etc.)

curly - Requires you to always put curly braces around blocks in loops and conditionals

esversion - The ECMAScript version to which the code must adhere

forin - Requires all `for in` loops to filter object's items with obj.hasOwnProperty()

freeze - Prohibits overwriting prototypes of native objects such as Array, Date and so on

funcscope - Suppresses warnings about declaring variables inside of control structures while accessing them later from the outside

futurehostile - Enables warnings about the use of identifiers which are defined in future versions of JavaScript

iterator - Suppresses warnings about the __iterator__ property.

latedef - Prohibits the use of a variable before it was defined

leanswitch - Prohibits unnecessary clauses within `switch` statements

maxcomplexity - Max cyclomatic complexity per function

maxdepth - Max depth of nested blocks

maxparams - Max number of formal parameters allowed per function

maxstatements - Max number statements per function

noarg - Prohibits the use of `arguments.caller` and `arguments.callee`
