#2796 - Repeat String

Easy • View on LeetCode • View on GitHub

Problem Description

Write code that enhances all strings such that you can call the string.replicate(x) method on any string and it will return repeated string x times.

Try to implement it without using the built-in method string.repeat.

Solution

/**
 * @param {number} times
 * @return {string}
 */
String.prototype.replicate = function(times) {
  let result = '';
  for (let i = 0; i < times; i++) {
    result += this;
  }
  return result;
};
