| * Creates an array of values by running each element of `array` thru `iteratee`. | |
| * The iteratee is invoked with three arguments: (value, index, array). | |
| * | |
| * @since 5.0.0 | |
| * @category Array | |
| * @param {Array} array The array to iterate over. | |
| * @param {Function} iteratee The function invoked per iteration. | |
| * @returns {Array} Returns the new mapped array. | |
| * @example | |
| * | |
| * function square(n) { | |
| * return n * n | |
| * } | |
| * | |
| * map([4, 8], square) | |
| * // => [16, 64] | |
