Reverse a string

reverseString.js

/* The old way:
const reverseString = (str) => {
  let reversed = '';
  for (let i = str.length - 1; i >= 0; i--) {
    const ch = str[i];
    reversed += ch;
  }
  return reversed;
};
const reverse = reverseString('javascript');
console.log(reverse); // tpircsavaj
*/
// The better way:
const reverseString = (str) => str.split('').reverse().join('');
const reverse = reverseString('javascript');
console.log(reverse); // tpircsavaj
