How do you reverse a string in place in JavaScript?

Question

How do you reverse a string in place (or in-place) in JavaScript when it is passed to a function with a return statement, without using built-in functions (.reverse()<

Answer 1

Reverse a String using built-in functions

function reverse(str) {
  // Use the split() method to return a new array
  //  Use the reverse() method to reverse the new created array
  // Use the join() method to join all elements of the array into a string
  return str.split("").reverse().join("");
}
console.log(reverse('hello'));

Reverse a String without the helpers

function reversedOf(str) {
  let newStr = '';
  for (let char of str) {
    newStr = char + newStr
    // 1st round: "h" + "" = h, 2nd round: "e" + "h" = "eh" ... etc. 
    // console.log(newStr);
  }
  return newStr;
}
console.log(reversedOf('hello'));
