[javascript] Repeat a string in JavaScript a number of times

Right pads with zeros with no arrays or loops. Just uses repeat() using ES6 2015, which has wide support now. Left pads if you switch the concatenation.

function pad(text, maxLength){ 
  var res = text + "0".repeat(maxLength - text.length);
  return res;
}

console.log(pad('hello', 8)); //hello000
