Want to reverse a string in place in JavaScript? As long as you’re dealing with simple ASCII characters, and you’re happy to use built-in functions, this will work:
1 2 3 | 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.
