reverse string javascript
// 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; }, ""); }
