+/**
+* 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 arr - The array to iterate over.
+* @param 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]
