/** |
|
* This method is like `_.difference` except that it accepts `iteratee` which |
|
* is invoked for each element of `array` and `values` to generate the criterion |
|
* by which they're compared. The order and references of result values are |
|
* determined by the first array. The iteratee is invoked with one argument: |
|
* (value). |
|
* |
|
* **Note:** Unlike `_.pullAllBy`, this method returns a new array. |
|
* |
|
* @static |
|
* @memberOf _ |
|
* @since 4.0.0 |
|
* @category Array |
|
* @param {Array} array The array to inspect. |
|
* @param {...Array} [values] The values to exclude. |
|
* @param {Function} [iteratee=_.identity] The iteratee invoked per element. |
|
* @returns {Array} Returns the new array of filtered values. |
|
* @example |
|
* |
|
* _.differenceBy([2.1, 1.2], [2.3, 3.4], Math.floor); |
|
* // => [1.2] |
|
* |
|
* // The `_.property` iteratee shorthand. |
|
* _.differenceBy([{ 'x': 2 }, { 'x': 1 }], [{ 'x': 1 }], 'x'); |
|
* // => [{ 'x': 2 }] |
