What are the best practices for type compatibility in TypeScript?

In TypeScript, best practices for type compatibility include using interfaces for object shapes, leveraging union types, and ensuring strict null checks.

Can you explain why using interfaces is important?

Using interfaces helps define clear contracts for objects, making your code more maintainable and easier to understand.

What are union types and how do they help with type compatibility?

Union types allow a variable to hold multiple types, enhancing flexibility and ensuring that your code can handle various scenarios.

How do strict null checks improve type safety?

Strict null checks prevent null and undefined from being assigned to variables unless explicitly allowed, reducing runtime errors.

Any tips for working with third-party libraries?

Always check for type definitions, use DefinitelyTyped for community types, and consider creating your own types when necessary.
