6. Hạn chế

While JS formatters offer numerous benefits, knowing their limitations is imperative. First, JS formatters rely on predefined rules and configurations, which may not align perfectly with every developer's coding style. It's crucial to balance code consistency and personal coding preferences. Additionally, JS formatters may struggle with complex or unconventional code patterns, requiring manual intervention in specific cases. It is worthwhile to review and test the formatted code to ensure it still functions as intended.
