- **Stateless** Each request from the client to the server contains all the information needed to fulfill that request. This means that the server doesn’t need to keep track of any state information.
- **Cacheable** Responses from the server can be cached by the client to reduce the number of requests made to the server.
- **Uniform interface** A uniform interface is used to communicate between the client and server, making it easier to understand and use.
- **Layered system** The architecture of the system can be broken down into layers, making it easier to maintain and update.
- **Code on demand** The server can execute code only when it’s required, which can be useful for scenarios where heavy processing is needed.
For example, let’s say you’re attending a music festival, and you want to check out the setlist for an upcoming band. You can use a REST API to make a request to the festival’s server, which will return the setlist in a format that your device can understand (e.g., JSON). The server will then query its database, retrieve the setlist, and send it back to your device.
In this case, the festival’s server is the client, and the API is acting as the server, providing the setlist data in a format that the client can understand. This is a simple example of how REST APIs can be used to enable communication between different systems.
As a programmer, I know that REST APIs can be used in a variety of scenarios, from web applications to mobile apps and even IoT devices. They provide a flexible and scalable way to build APIs that are reliable and easy to maintain.

REST API
As a programmer, I know that REST API is a hot topic in the tech world, but what exactly does it mean When I searched for the term, I found that many people were asking the same question What is a REST API
To clarify, a REST API, or Representational State of Resource, is an architectural style for designing networked applications. It’s a way to build APIs that are easy to use, maintain, and scale. In short, REST APIs provide a way for two systems to communicate with each other, typically over the internet, using a pre-defined protocol. This allows different systems, such as a web application and a database, to talk to each other and exchange data.
Here are some key benefits and examples of REST APIs
