Note that the `replaceAll` method still requires that a *global* regular expression is used, however by using this method it's immediately obvious when looking at the code that all occurrences will be replaced; please see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replaceAll#parameters Please find additional details at https://github.com/sindresorhus/eslint-plugin-unicorn/blob/main/docs/rules/prefer-string-replace-all.md
