// 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;
return res;
}
// using REDUCE ( high order array function )
function reverse3(str) {
return str.split("").reduce((output, char) => {
return char + output;
}, "");

reverseString("hello");javascript how to reverse a string
function reverseString(str) {
// Step 1. Use the split() method to return a new array
var splitString = str.split(""); // var splitString = "hello".split("");
// ["h", "e", "l", "l", "o"]
// Step 2. Use the reverse() method to reverse the new created array
var reverseArray = splitString.reverse(); // var reverseArray = ["h", "e", "l", "l", "o"].reverse();
// ["o", "l", "l", "e", "h"]
// Step 3. Use the join() method to join all elements of the array into a string
var joinArray = reverseArray.join(""); // var joinArray = ["o", "l", "l", "e", "h"].join("");
// "olleh"
//Step 4. Return the reversed string
return joinArray; // "olleh"
