Answer 1

This reverse prototype function is implemented using "this". If you see log console of "this", it will generate the array, and it has length property. So that it!!! Just use reverse "for-loop" as shown in the code snippet.

String.prototype.reverse = function () {
    console.log(this);
    var result = "";
    var len = this.length;
    
    for (i = (len-1); i >= 0 ; i--) {
        result += this[i];
    }
    return result;
};

alert("elahnu jaknap".reverse());
