Installation

Spotlight.js’ only hard dependency is lodash.

In a browser:

<script src="lodash.js"></script>
<script src="spotlight.js"></script>

In an AMD loader:

require({
  'paths': {
    'spotlight': 'path/to/spotlight',
    'lodash': 'path/to/lodash'
  }
},
['spotlight'], function(spotlight) {/*…*/});

Using npm:

$ npm i --save spotlight

In Node.js:

var spotlight = require('spotlight');

Usage example:

// find all "length" properties
spotlight.byName('length');

// or find all "map" properties on jQuery
spotlight.byName('map', { 'object': jQuery, 'path': '$' });

// or all properties with `jQuery` objects
spotlight.byKind(jQuery);

// or all properties with `RegExp` values
spotlight.byKind('RegExp');

// or all properties with `null` values
spotlight.byKind('null');

// or all properties with `undefined` values
spotlight.byKind('undefined');

// or all constructors
spotlight.byKind('constructor');

// or all properties with the value `0`
spotlight.byValue(0);

// or all properties containing "oo" in their name
spotlight.custom(function(value, key) { return key.indexOf('oo') > -1; });

// or all properties with falsey values
spotlight.custom(function(value) { return !value; });
