How do you reverse a string in place in JavaScript?

Question

How do you reverse a string in place (or in-place) in JavaScript when it is passed to a function with a return statement, without using built-in functions (.reverse()<

Answer 1

You can't because JS strings are immutable. Short non-in-place solution

[...str].reverse().join``

let str = "Hello World!";
let r = [...str].reverse().join``;
console.log(r);
