/**
|
||
|
|
* Iterates over elements of 'arr' from right to left and invokes 'callback' for each element.
|
||
|
|
*
|
||
|
|
* @template T - The type of elements in the array.
|
||
|
|
* @param {T[]} arr - The array to iterate over.
|
||
|
|
* @param {(value: T, index: number, arr: T[]) => void} callback - The function invoked per iteration.
|
||
|
|
* The callback function receives three arguments:
|
||
|
|
* - 'value': The current element being processed in the array.
|
||
|
|
* - 'index': The index of the current element being processed in the array.
|
||
|
|
* - 'arr': The array 'forEachRight' was called upon.
|
||
|
|
*
|
||
|
|
* @example
|
||
|
|
* const array = [1, 2, 3];
|
||
|
|
* const result: number[] = [];
|
||
|
|
*
|
||
|
|
* // Use the forEachRight function to iterate through the array and add each element to the result array.
|
||
|
|
* forEachRight(array, (value) => {
|
||
|
|
* result.push(value);
|
||
|
|
* })
|
||
|
|
*
|
||
|
|
* console.log(result) // Output: [3, 2, 1]
