Jan 29, 2025 · // JavaScript program to reverse a string using backward traversal function reverseString (s) {let res = []; // Traverse on s in backward direction // and add each character to the array for (let i = s. length-1; i >= 0; i--) {res. push (s [i]);} return res. join ('');} const s = "abdcfe"; console. log (reverseString (s));

Jun 17, 2024 · To reverse a string in place using a for loop in JavaScript, iterate over half the string length, swapping characters from both ends until reaching the middle. Return the modified string.

As long as you're dealing with simple ASCII characters, and you're happy to use built-in functions, this will work: return s.split("").reverse().join(""); If you need a solution that supports UTF-16 or other multi-byte characters, be aware that this function will give invalid unicode strings, or valid strings that look funny.

Oct 31, 2011 · Upon each iteration the upper half’s value (calculated by deducting the current position by the string length) is temporary stored and replaced by the lower half’s value. The temporary value then replaces the lower half’s value to finally result in a reversed string.

Aug 15, 2017 · Here is the simplest way to do without using any javascript inbuilt function. let r = ""; for(let i = str.length-1; i >= 0; i--){ r += str[i]; return r; Create a new string and add all the chars from the original string to it backwards: var r = ""; for(var i = str.length - 1; i >= 0; i--){ r += str.charAt(i); return r; Then just say:

Mar 14, 2016 · For this solution, we will use three methods: the String.prototype.split () method, the Array.prototype.reverse () method and the Array.prototype.join () method. The split () method splits a String object into an array of string by separating the string into sub strings. The reverse () method reverses an array in place.

Jan 10, 2025 · We have given an input string and the task is to reverse the input string in JavaScript. The split () method divides the string into an array of characters, reverse () reverses the array, and join () combines the reversed characters into …
