Javascript - Loop through array backwards with forEach

Question

Is there a way to loop backwards through an array using forEach (not any other kind of loop, I know how to do with with a for / standard ways) and without actua

Answer 1

array.forEach has 3 parameters. You can use these to effectively forEach backward.

var arr = [1, 2, 3];

    arr.forEach(function(x, index, the_array) {
        let x_prime = the_array[the_array.length-1-index]
        console.log(x_prime);
    })

will print
