What are the differences between decorators and services in programming?

Decorators are design patterns that allow behavior to be added to individual functions or methods dynamically. Services, on the other hand, are typically classes or modules that provide specific functionality and can be reused across an application.

Can you give me an example of a decorator?

Sure! A common example is the @app.route decorator in Flask, which is used to define routes for web applications.

And what about a service? How is it structured?

A service in a web application might be a class that handles data fetching from an API. It usually has methods like fetchData() and can be injected into components that need it.

When should I use a decorator instead of a service?

Use decorators when you want to add functionality to existing methods without modifying their structure. Use services for reusable logic that can be shared across different parts of your application.
