 # Use of `String#replaceAll` with a first argument which is not a regular expression
 
-Using `String.replaceAll` is less performant than `String.replace` when the first argument is not a regular expression.
+Using `String#replaceAll` is less performant than `String#replace` when the first argument is not a regular expression.
 
 ## Overview
 
-The underlying implementation of `String.replaceAll` uses `Pattern.compile` and expects a regular expression as its first argument. However in cases where the argument could be represented by just a plain `String` that does not represent an interesting regular expression, a call to `String.replace` may be more performant as it does not need to compile the regular expression.

 ## Recommendation
 
-Use `String.replace` instead where a `replaceAll` call uses a trivial string as its first argument.
