 * Creates a slice of `array` from `start` up to, but not including, `end`.

 * returned.

 * @since 3.0.0
 * @category Array
 * @param {Array} array The array to slice.
 * @param {number} [start=0] The start position.
 * @param {number} [end=array.length] The end position.
 * @returns {Array} Returns the slice of `array`.
