JavaScript Reverse
JavaScript has no native reverse for strings, so we chain three array methods: split("") breaks the string into characters, reverse() flips the array, and join("") glues it back. Another textbook chaining example.
Syntax
str.split('').reverse().join('')Examples
| Input | Arguments | Output |
|---|---|---|
| "hello" | — | "olleh" |
Gotchas
- split("") breaks emoji and some Unicode characters apart; use [...str] for correct code-point handling.
