Reverse a String in JavaScript: 2 Easy Methods

// create a function that takes a string as an argument
function reverseString(str) {
  // use the split() method to split the string into an array of characters
  var strArray = str.split("");

  // use the reverse() method to reverse the order of the characters in the array
  var reversedArray = strArray.reverse();

  // use the join() method to join the characters back into a string
  var reversedString = reversedArray.join("");

  // return the reversed string
  return reversedString;
}

// call the function and pass a string as an argument
reverseString("hello"); // will return "olleh"

// create a function that takes a string as an argument
function reverseString(str) {
  // use the reduce() method to iterate over the characters in the string
  // and build a new string in reverse order
  var reversedString = str.split("").reduce((rev, char) => char + rev, "");

  // return the reversed string
  return reversedString;
}

// call the function and pass a string as an argument
reverseString("hello"); // will return "olleh"
