REST APIs

Summary

An architectural style for designing web APIs around resources and standard HTTP methods (GET, POST, PUT, DELETE) with predictable, stateless endpoints. Good REST APIs also define consistent resource naming, status codes, validation, pagination, error responses, authentication, and versioning so different clients can integrate predictably.

• 1Call a public REST API (e.g. a joke or weather API) using `fetch`. Validate your understanding by applying it in a small practical example.
• 2Learn the meaning of each HTTP verb and when to use it. Focus on understanding the underlying reason it works, not only memorizing the definition.
• 3Read about REST constraints: statelessness, resource-based URLs, uniform interface.
