javascript loop through array backwards

# Using Array.prototype.reverse() function

var arr = [1, 2, 3, 4, 5];
 
arr.slice().reverse()
    .forEach(function(item) {
            console.log(item);
        });

# Alternatively, you can use the Object.keys() method to get keys:

var arr = [1, 2, 3, 4, 5];
 
Object.keys(arr).reverse()
        .forEach(function(index) {
            console.log(arr[index]);
        });
