Repeat String - Javascript

Question

What is the best or most concise method for returning a string repeated an arbitrary amount of times?

The following is my best shot so far:

function          


        

Answer 1

To repeat a string in a specified number of times, we can use the built-in repeat() method in JavaScript.

Here is an example that repeats the following string for 4 times:

const name = "king";

const repeat = name.repeat(4);

console.log(repeat);

Output:

"kingkingkingking"

or we can create our own verison of repeat() function like this:

function repeat(str, n) {
  if (!str || !n) {
    return;
  }

 let final = "";
  while (n) {
    final += s;
    n--;
  }
  return final;
}

console.log(repeat("king", 3))
