Simple loop usage for string reversal (without using reverse())

stringReversalv1.js

//String reverse function with for loop
String.prototype.reverseString = function(){
s=[...this]; r=[];
for(i=0;;){if(i!=s.length){r.push(s.pop())}else{break;}}
return r.join('');
}
//Sample usage: "thisisreversed12".reverseString();
//Output from usage
//"21desreversisiht"
