JavaScript: Execute a provided function once for each array element, starting from the array's last element

JavaScript fundamental (ES6 Syntax): Exercise-76 with Solution

Write a JavaScript program to execute a provided function once for each array element, starting with the array's last element.

• Use Array.prototype.slice() to clone the given array and Array.prototype.reverse() to reverse it.
• Use Array.prototype.forEach() to iterate over the reversed array.

Sample Solution:

JavaScript Code:

//#Source https://bit.ly/2neWfJ2 
const forEachRight = (arr, callback) =>
  arr
    .slice(0)
    .reverse()
    .forEach(callback);
forEachRight([1, 2, 3, 4], val => console.log(val));

Sample Output:
