/** |
|
* This method is like `_.set` except that accepts `updater` to produce the |
|
* value to set. Use `_.updateWith` to customize `path` creation. The `updater` |
|
* is invoked with one argument: (value). |
|
* |
|
* **Note:** This method mutates `object`. |

|
* @param {Object} object The object to modify. |
|
* @param {Array|string} path The path of the property to set. |
|
* @param {Function} updater The function to produce the updated value. |
|
* @returns {Object} Returns `object`. |
|
* @example |
|
* |
|
* var object = { 'a': [{ 'b': { 'c': 3 } }] }; |
|
* |
|
* _.update(object, 'a[0].b.c', function(n) { return n * n; }); |
|
* console.log(object.a[0].b.c); |
|
* // => 9 |
|
* |
|
* _.update(object, 'x[0].y.z', function(n) { return n ? n + 1 : 0; }); |
|
* console.log(object.x[0].y.z); |
|
* // => 0 |
