xxxInPlace or xxxCopy?

Strings are meant to be immutable, and the functional style is simpler to understand and safer to use, so I firmly suggest the default (with shorter names) functions to create a new string/array, and the versions that work in place with a longer name.

In some languages the versions that work in-place have a bang (!) suffix, like replace and replace!. I guess a name like "replaceBang" is too much cryptic.

You probably meant:
