Repeat String X Times in Javascript


"a".repeat(10)

The code below is written using ES6 syntaxes but could just as easily be written in ES5 or even less. ES6 is not a requirement to create a "mechanism to loop x times"

If you don't need the iterator in the callback, this is the most simple implementation

const times = x => f => {
  if (x > 0) {
    f()
    times (x - 1) (f)
  }
}

Example 2


function repeatStringNumTimes(string, times) {
  var repeatedString = "";
  while (times > 0) {
    repeatedString += string;
    times--;
  }
  return repeatedString;
}
repeatStringNumTimes("abc", 3);

Example 3


function repeatStringNumTimes(string, times) {
  if(times < 0) 
    return "";
  if(times === 1) 
    return string;
  else 
    return string + repeatStringNumTimes(string, times - 1);
}
repeatStringNumTimes("abc", 3);
