/**
 * Returns a shallow copy of a portion of an array into a new array object selected from begin to end (end not included). The original array will not be modified.

 * @function
 * @since v0.0.13
 * @category lang
 * @param {Array} arrayLike The array like value to slice values from
 * @param {number} start [=0] Zero-based index at which to begin extraction. A negative index will be treated as an offset from the end.
 * @param {number} end [=array.length] Zero-based index before which to end extraction. `arrayLikeSlice` extracts up to but not including end.
 * @returns {Array} A new array with the extraced values
 * @example
 *
 * arrayLikeSlice(['a', 'b', 'c'], 0, 2)
 * //=> ['a', 'b']
