/** |
|
* This method is like `_.uniq` except that it accepts `iteratee` which is |
|
* invoked for each element in `array` to generate the criterion by which |
|
* uniqueness is computed. The order of result values is determined by the |
|
* order they occur in the array. The iteratee is invoked with one argument: |
|
* (value). |
|

* @memberOf _ |
|
* @since 4.0.0 |
|
* @category Array |
|
* @param {Array} array The array to inspect. |
|
* @param {Function} [iteratee=_.identity] The iteratee invoked per element. |
|
* @returns {Array} Returns the new duplicate free array. |
|
* @example |
|
* |
|
* _.uniqBy([2.1, 1.2, 2.3], Math.floor); |
|
* // => [2.1, 1.2] |
|
* |
|
* // The `_.property` iteratee shorthand. |
|
* _.uniqBy([{ 'x': 1 }, { 'x': 2 }, { 'x': 1 }], 'x'); |
|
* // => [{ 'x': 1 }, { 'x': 2 }] |
