Unable to reverse a string in javascript

Question

Wanted to make reverse string without using the loop I am getting an array

function reverseString(str) {
  return str
    .split("")
    .reverse();
}
console.log(reverseString('coder'));

Answer 1

.split() creates an Array; after doing .reverse() it's still an Array.

Use Array.prototype.join() to return a String:

function reverseString(str) {
  return str
    .split("")
    .reverse()
    .join("");
}
console.log(reverseString('coder'));

Answer 2

You forgot .join("") after reverse;
