# unicorn/prefer-string-replace-all

> Require `replaceAll()` instead of `replace()` with a global regex

`replace()` only replaces every match if the regex has the `g` flag, and one letter at the end of a pattern is easy to miss. `replaceAll()` says it in the name.

The rule also reports a regex passed to `replaceAll()` when it only matches one fixed string, because a plain string does the same thing and doesn't need escaping.

`--fix` renames the method, and turns the regex into a string when it matches one fixed string.
