Replace backward slashes with forward slashes - JavaScript

JavascriptWeb DevelopmentFront End TechnologyObject Oriented Programming

We are required to write a JavaScript function that takes in a string that may contain some backward slashes. The function should return a new string with all the backward slashes replaced with forward slashes.

Let’s say the following is our string −

const str = 'Th/s str/ng /conta/ns some/ forward slas/hes';


Following is the code −

const str = 'Th/s str/ng /conta/ns some/ forward slas/hes';
const invertSlashes = str => {
   let res = '';
   for(let i = 0; i < str.length; i++){
      if(str[i] !== '/'){
         res += str[i];
      res += '\\';
   return res;


This will produce the following output in console −

Th\s str\ng \conta\ns some\ forward slas\hes
