String.prototype.times = function(count) {
count = (count >> 0);
var t = (count > 1? this.times(count / 2): ”);
return t + (count % 2? t + this: t);
};
//use ‘x’.times(1000000)

//– adds a multiplier function to any string object
//– use: String.x(number)
//– example:
//– var str=’hi’;
//– str.x(3);
//– returns: hihihi

String.prototype.x=function(x){
if(arguments.length==0)return this;
if(x<=0)return this;
var out=”;
for(i=0;i<x;i++){
out+=this
}
return out;
}

this is useful since you can add it to any other built in string modifier
eg.
string.replace(/hi/,’bye’).x(10)

Thank you all for this great thread

function mulDaghan(str,count){
    if(count==0) return '';
    var binaryCount = count.toString(2);
    var numDegree = binaryCount.length;
    var resultStr='';
    for(var i=0; i<numDegree; i++){
        resultStr+=resultStr; // for both 0 and 1
        if(binaryCount.charAt(i) == '1'){
            resultStr+=str;
        }
    }
    return resultStr;
