Can you recall the principles of REST?

REST (Representational State Transfer) is an architectural style for creating web services based on several key principles:

• Client-server architecture: clients and servers are separated, allowing them to evolve independently.
• Stateless: each request from a client to a server must contain all the information needed to process it; the server does not store state between requests.
• Caching: responses should explicitly indicate whether they can be cached to improve performance.
• Uniform interface: use of standard HTTP methods (GET, POST, PUT, DELETE, etc.) and uniform resource identifiers (URIs).
• Layered system: architecture can consist of multiple layers, such as proxies, load balancers.
• Code on demand (optional): the server can transfer executable code to the client (e.g., JavaScript).

These principles ensure simplicity, scalability, and flexibility of web services.
