* Takes elements from the end of the array while the predicate function returns `true`.
|
|
*
|
|
* @template T - Type of elements in the input array.
|
|
*
|
|
* @param {T[]} arr - The array to take elements from.
|
|
* @param {(item: T, index: number, array: readonly T[]) => boolean} shouldContinueTaking - The function invoked per element with the item, its index, and the array.
|
|
* @returns {T[]} A new array containing the elements taken from the end while the predicate returns `true`.
|
|
*
|
|
* @example
|
|
* // Returns [3, 2, 1]
|
|
* takeRightWhile([5, 4, 3, 2, 1], n => n < 4);
|
|
*
|
|
* @example
|
|
* // Returns []
|
|
* takeRightWhile([1, 2, 3], n => n > 3);
|
|
*
|
|
* @example
|
|
* // Using index parameter
|
|
* takeRightWhile([10, 20, 30, 40], (x, index) => index > 1);
|
|
* // Returns: [30, 40]
