Question

Which of the followingfunction is used to reverse the string

Answer 1

Answer:

As long as you're dealing with simple ASCII characters, and you're happy to use built-in functions, this will work:

function reverse(s){

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. You might want to consider this answer instead.

[...s] is Unicode aware, a small edit gives:-

function reverse(s){

return [...s].reverse().
