How do I handle errors and exceptions properly?

Proper error handling is essential:

1. Use Try-Catch Blocks

Wrap risky code in try-catch to handle exceptions gracefully without crashing.

2. Be Specific

Catch specific exceptions rather than generic ones to handle different errors appropriately.

3. Log Errors

Always log errors with context - timestamp, user, action, stack trace for debugging.

4. User-Friendly Messages

Show helpful messages to users, hide technical details that could be security risks.

5. Fail Gracefully

Provide fallback behavior when possible instead of complete failure.

6. Validate Inputs

Prevent errors by validating all inputs before processing.

7. Use Error Boundaries

In frontend apps, use error boundaries to prevent entire app crashes.

8. Monitor Production

Use error tracking services like Sentry to catch issues in production.

My application crashes sometimes due to unhandled errors. What is the best way to implement error handling and exception management in my code?
