| /** | |
| * Invokes the method at `path` of each element in `collection`, returning | |
| * an array of the results of each invoked method. Any additional arguments | |
| * are provided to each invoked method. If `path` is a function, it's invoked | |
| * for, and `this` bound to, each element in `collection`. | |
| * | |
| * @since 4.0.0 | |
| * @category Collection | |
| * @param {Array|Object} collection The collection to iterate over. | |
| * @param {Array|Function|string} path The path of the method to invoke or | |
| * the function invoked per iteration. | |
| * @param {Array} [args] The arguments to invoke each method with. | |
| * @returns {Array} Returns the array of results. | |
| * @example | |
| * | |
| * invokeMap([[5, 1, 7], [3, 2, 1]], 'sort') | |
| * // => [[1, 5, 7], [1, 2, 3]] | |
| * | |
| * invokeMap([123, 456], String.prototype.split, ['']) | |
| * // => [['1', '2', '3'], ['4', '5', '6']] | |
