Repeating a string n number of times in JavaScript

Learn, how to repeat a string in JavaScript.

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"

Similarly, we can also create our repeat() function like this:

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

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

console.log(repeat("sai", 3)); // "saisaisai"

In the above function, we have used the while loop to concatenate the string for n number of times.
