How to register a route in WordPress REST API?

To register routes you should use the register_rest_route() function. It needs to be called on the rest_api_init action hook. register_rest_route() handles all of the mapping for routes to endpoints. Let’s try to create a “Hello World, this is the WordPress REST API” route.
