| * Creates a slice of `array` with `n` elements dropped from the end. | |

| * @since 3.0.0 | |
| * @category Array | |
| * @param {Array} array The array to query. | |
| * @param {number} [n=1] The number of elements to drop. | |
| * @returns {Array} Returns the slice of `array`. | |
| * @example | |
