// hey buddy, here are different implementations, choose your favourite !!


// best implementation
const reverse = (str) => str.split("").reverse().join("");


// explanation
function reverse1(str) {

  // array as an individual element
  const arr = str.split("");

  // swap all the indexes of the array
  arr.reverse();

  // join every element back together
  const res = arr.join("");
  return res;
}


//  without using REVERSE method
//  recursive function
function reverse2(str) {
  let res = "";
  for (let i = 0; i < str.length; i++) res = str[i] + res;
  return res;
}


// using REDUCE ( high order array function )
