Subject: [PATCH] refactor(read_only_code): simplify first format replacer

* simplified regex, by using the `s` flag
  * https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_expressions#advanced_searching_with_flags

* use template literal instead of string concat
* use arrow function
