10 * Adds all own enumerable string keyed function properties of a source
11 * object to the destination object. If `object` is a function, then methods
12 * are added to its prototype as well.
13 *
14 * **Note:** Use `_.runInContext` to create a pristine `lodash` function to
15 * avoid conflicts caused by modifying the original.
16 *
17 * @static
18 * @since 0.1.0
19 * @memberOf _
20 * @category Util
21 * @param {Function|Object} [object=lodash] The destination object.
22 * @param {Object} source The object of functions to add.
23 * @param {Object} [options={}] The options object.
24 * @param {boolean} [options.chain=true] Specify whether mixins are chainable.
25 * @returns {Function|Object} Returns `object`.
26 * @example
27 *
28 * function vowels(string) {
29 * return _.filter(string, function(v) {
30 * return /[aeiou]/i.test(v);
31 * });
32 * }
33 *
34 * _.mixin({ 'vowels': vowels });
35 * _.vowels('fred');
36 * // => ['e']
37 *
38 * _('fred').vowels().value();
39 * // => ['e']
40 *
41 * _.mixin({ 'vowels': vowels }, { 'chain': false });
42 * _('fred').vowels();
43 * // => ['e']
