| /** |
| * Performs a deep comparison between two values to determine if they are |
| * equivalent. If `customizer` is provided it's invoked to compare values. |
| * If `customizer` returns `undefined` comparisons are handled by the method |
| * instead. The `customizer` is bound to `thisArg` and invoked with up to |
| * three arguments: (value, other [, index|key]). |
| * |
| * **Note:** This method supports comparing arrays, booleans, `Date` objects, |
| * numbers, `Object` objects, regexes, and strings. Objects are compared by |
| * their own, not inherited, enumerable properties. Functions and DOM nodes |
| * are **not** supported. Provide a customizer function to extend support |
| * for comparing other values. |

| * @param {*} value The value to compare. |
| * @param {*} other The other value to compare. |
| * @param {Function} [customizer] The function to customize value comparisons. |
| * @param {*} [thisArg] The `this` binding of `customizer`. |
| * @returns {boolean} Returns `true` if the values are equivalent, else `false`. |
| * @example |
| * |
| * var object = { 'user': 'fred' }; |
| * var other = { 'user': 'fred' }; |
| * |
| * object == other; |
| * // => false |
| * |
| * _.isEqual(object, other); |
| * // => true |
| * |
| * // using a customizer callback |
| * var array = ['hello', 'goodbye']; |
| * var other = ['hi', 'goodbye']; |
| * |
| * _.isEqual(array, other, function(value, other) { |
| * if (_.every([value, other], RegExp.prototype.test, /^h(?:i|ello)$/)) { |
| * return true; |
| * } |
| * }); |
| * // => true |
