Javascript, repeating an object key N-times, being N its value

Question

I was wondering how to do this in the more cleaner and optimal way:

I have an Object with the following structure:

{
   \"125\": 2,
   \"439\": 3,
           


        

Answer 1

Hmm... not sure if I got at, but maybe something like this:

var myObj = {
   "125": 2,
   "439": 3,
   "560": 1,
   "999": 2
},
myArray = [];

for(k in myObj){
    for(i = 0; i < myObj[k]; i++){
        myArray.push(k);
    }
}
console.log(myArray)
