What are the differences between TypeScript decorators and middleware?

TypeScript decorators are special annotations that can modify classes, methods, or properties at design time. Middleware, on the other hand, is a function that processes requests in a web application, typically at runtime.

Can you give me an example of how decorators are used in TypeScript?

Sure! A common use of decorators is in Angular, where you might use the @Component decorator to define a component's metadata.

And how does middleware work in a Node.js application?

In a Node.js app, middleware functions can be used to handle requests, modify request and response objects, or end the request-response cycle.

Which one is better for handling cross-cutting concerns?

It depends on the context. Decorators are great for adding metadata and behavior to classes, while middleware is more suited for handling requests and responses in web applications.
