Enable these options to *not* throw errors in these conditions.

    /* jshint asi: true */
    allow()

    /* jshint boss: true */
    if (m = str.match(/.../))

    /* jshint debug: true */
    debugger;

    /* jshint eqnull: true */
    if (x == null)

    /* jshint evil: true */
    eval('...')

    /* jshint expr: true */
    production && minify = true;
    div.innerWidth;
    expect(x).be.true;

    /* jshint laxcomma: true */
    var one = 1
      , two = 2;

    /* jshint loopfunc: true */
    for (i=0; i<10; x++) {
      (function(i) { ... })(i);
    }

    /* jshint sub: true */
    process.env['name_here']

Enable these options to catch more errors.

      shuffle();

    /* jshint eqeqeq: true */
    if (a == null)                  // err: use ===

    /* jshint es3: true */          // ...for legacy IE compatibility
    a.default = function() { ... }; // err: reserved word
    array = [ 1, 2, 3, ];           // err: extra comma

    /* jshint forin: true */
    for (key in obj) { ... }        // err: check obj.hasOwnProperty(key)

    /* jshint freeze: true */
    Array.prototype.count = ...;    // err: don't modify native prototypes

    /* jshint indent: 4 */
    if (x) {                        // err: expected indent of 4, found 2
      ...;
    }

    /* jshint quotmark: single */
    /* jshint quotmark: double */
    alert("hi");                    // err: only single allowed

    /* jshint strict: true */
    function() { ... }              // err: need "use strict"
