RESTful design is the language of the modern web, allowing diverse systems to interact seamlessly.
1The Resource Concept
Resources are the nouns of your API. Instead of having URLs like /getUsers, REST uses /users and relies on HTTP methods to determine the action.
2Uniform Interface
A consistent interface simplifies architecture. By using standard HTTP status codes (like 200 OK or 404 Not Found) and JSON as a data format, your API becomes predictable and easy to consume.
3Statelessness & Scaling
Because the server doesn't need to remember who the client is between requests, scaling becomes much easier. You can add more servers without worrying about session synchronization.
