How Can Test Driven Development (TDD) Help with Code Maintainability?

Test Driven Development (TDD) enhances code maintainability by ensuring that code is modular, reliable, and easily modifiable. Here's how:

1. Early Bug Detection: Writing tests first helps catch issues early, preventing complex problems that would be harder to fix later.
2. Cleaner Code: TDD encourages writing simple, well-structured, and modular code, making it easier to maintain.
3. Easier Refactoring: With a solid test suite in place, developers can safely refactor code without breaking existing features.
4. Comprehensive Test Coverage: TDD ensures that all functionality is tested, making future updates or changes easier to manage.

In conclusion, Test Driven Development (TDD) promotes sustainable, maintainable code by providing a clear structure, early issue detection, and robust test coverage.
