MEANING OF RREST API code example

Example 1: rest api means

Let's break it into two components:

1) RESTful
2) API
An API is an interface through which one program or web site talks to another.
They are used to share data and services, and they come in many different
formats and types.

A RESTful API is one of the many possible ways that programs, servers, 
and web sites can share data and services. REST (Representational State Transfer
) describes the general rules for how the data and services are represented 
through the API so that other programs will be able to correctly request and 
receive the data and services that an API makes available

Example 2: rest api

Representational state transfer is a software architectural style that defines
a set of constraints to be used for creating Web services.

Web services that conform to the REST architectural style, called RESTful Web
services, provide interoperability between computer systems on the internet
