研究方向
Identify the core classes in the js beautify codebase, likely located in the 'src' or 'js' directory. Review existing test files (if any) to understand the test framework used. Check the issue comments for any additional context or guidance from maintainers. Determine which unit test framework to use (e.g., Mocha or Jest) and write tests covering core functionality.
