How to handle exceptions in TypeScript with type safety?

Thank you for the question. Handling exceptions with type safety in TypeScript is crucial for building robust and maintainable applications. TypeScript provides several features to ensure that exception handling can be both effective and type-safe. Let me walk you through a few strategies that I've successfully implemented in my previous roles, specifically as a Software Engineer focusing on TypeScript applications. First, leveraging TypeScript's strong typing system to define custom error classes is a foundational step. By extending the native Error class, you can create specific error types for different parts of your application. This approach not only makes the code more readable but also ensures that errors can be caught and handled specifically according to their type. For instance, defining a DatabaseError class for errors related to database operations, and a ValidationError class for errors occurring from data validation...
