Question

The best way to explain this is with examples.

Let’s say I have the integer 5. I plug it into a function, and it would return the space character (” “) 5 times in a single variable, like ”     “.

I have the integer 3. I plug it into a function, and the output would be ”   ” (3 spaces).

Hopefully you get the point. What is the best way to accomplish this. I feel like there is a really simple way to do this in JavaScript, with or without loops, that I am missing. Thanks.

Answer 1

function spaces(size) {
    for(var output = ""; size > 0; size--) output += " ";
    return output;
}

A shorter version 🙂

function spaces(n) {
    for(var s="";n--;s+=" "){}return s;
}
