| /** |
| * Performs a deep comparison between two values to determine if they are |
| * equivalent to each other. If a callback is provided it will be executed |
| * to compare values. If the callback returns `undefined` comparisons will |
| * be handled by the method instead. The callback is bound to `thisArg` and |
| * invoked with two arguments; (a, b). |
| * |
| * @static |
| * @memberOf _ |
| * @category Objects |
| * @param {*} a The value to compare. |
| * @param {*} b The other value to compare. |
| * @param {Function} [callback] The function to customize comparing values. |
| * @param {*} [thisArg] The `this` binding of `callback`. |
| * @returns {boolean} Returns `true` if the values are equivalent, else `false`. |
| * @example |
| * |
| * var object = { 'name': 'fred' }; |
| * var copy = { 'name': 'fred' }; |
| * |
| * object == copy; |
| * // => false |
| * |
| * _.isEqual(object, copy); |
| * // => true |
| * |
| * var words = ['hello', 'goodbye']; |
| * var otherWords = ['hi', 'goodbye']; |
| * |
| * _.isEqual(words, otherWords, function(a, b) { |
| * var reGreet = /^(?:hello|hi)$/i, |
| * aGreet = _.isString(a) && reGreet.test(a), |
| * bGreet = _.isString(b) && reGreet.test(b); |
| * |
| * return (aGreet || bGreet) ? (aGreet == bGreet) : undefined; |
| * }); |
| * // => true |
