Best Practices for Non-blocking Code
When writing robust, non-blocking JavaScript code, you should always focus on maintaining code clarity, reliability, and performance. Keeping asynchronous code easy to read and understand is essential, especially as your codebase grows.
- Use
asyncandawaitfor readability: these features make complex asynchronous flows much easier to follow than deeply nested callbacks; - Always handle errors: ensure that every asynchronous operation has proper error handling—uncaught errors can silently break your application or lead to confusing bugs;
- Avoid blocking the main thread: offload heavy computations or I/O operations to asynchronous tasks so the user interface remains responsive.
- Prevent deeply nested callbacks: minimize callback nesting by using promises or async functions, which help prevent callback hell and make your logic more maintainable.
- Review for bottlenecks: regularly check your code for potential performance issues and ensure that long-running tasks never block the event loop.
Keep async code simple, always handle errors, and avoid blocking the main thread.
