oxc/bad-replace-all-arg
Require the g flag on a regular expression passed to replaceAll()
replaceAll() throws a TypeError when its regular expression doesn't have the g flag. The code parses and only fails when that line runs.
The rule checks a regular expression literal, new RegExp() and RegExp(), written in the call or kept in a variable. If the flags aren't a plain string, it can't tell and reports nothing. A string argument is fine, because replaceAll() replaces every occurrence of it.
