Short Answer: Yes, they are immutable. If you want a more in depth explanation, you can find a pretty good one here: Immutability in JavaScript.

In fact, no string methods change the string they operate on, they all return new strings. The reason is that strings are immutable – they cannot change, we can only ever make new strings.
