This is a pretty small grammar. The injection for comments is already set up in runtime/queries/javascript/injections.scm. Github also uses this for their syntax highlighting, like in:

/**
 * Extract the string matched by the regex and return both the resulting string
 * and the matched string
 *
 * @param {string} source
 * @param {RegExp} regExp
 * @returns
 */
export function extract(source, regExp) {
  const result = regExp.exec(source)
  return result ? {
    normalizedSource: source.replace(result[0], ''),
    extracted: result[1]
  } : { normalisedSource: source, extracted: '' }
}
