// hey buddy, here are different implementations, choose your favourite !!
// best implementation
const reverse = (str) => str.split("").reverse().join("");
// explanation
function reverse1(str) {
// turn string to array, each char of the string will be part of the
// 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;

}
// using REDUCE ( high order array function )
