Function-based Views vs Class-based Views in Django

What are the main differences between function-based views and class-based views in Django?

Function-based views (FBVs) are simple Python functions that take a web request and return a web response. Class-based views (CBVs), on the other hand, are Python classes that provide more structure and reusability by allowing you to define methods for different HTTP methods.

When should I use function-based views instead of class-based views?

You might prefer function-based views for simpler views where you don't need the extra functionality of class-based views. They are easier to read and understand for straightforward tasks.

Can you give me an example of when to use class-based views?

Class-based views are great for complex views that require multiple methods, like handling different HTTP methods or when you want to reuse code across similar views. For instance, a view that handles both GET and POST requests for a form submission.

Are there any performance differences between the two?

Generally, the performance difference is negligible. The choice between FBVs and CBVs should be based on code organization and maintainability rather than performance.
