REST Principles

Resource-based: REST APIs are designed around resources, which are identified by unique URIs (Uniform Resource Identifiers).
Stateless: Each request from the client to the server must contain all the necessary information for the server to understand and process the request. The server should not rely on storing any client context between requests.
Cacheable: Responses from the server should be labeled as cacheable or non-cacheable, allowing clients to cache responses and improve performance.
Uniform Interface: REST APIs should follow a consistent interface, using standard HTTP methods (GET, POST, PUT, DELETE) to perform operations on resources.
Layered System: REST APIs can be composed of multiple layers, allowing for load balancing, caching, and proxy servers.

Async generators was a powerful one from ES9.

When I use String.raw I’m saying: Just give me what I give you. Don’t process anything..

As applications grow in size and as the conditions become more complex, instead of stuffing multiple conditions inside a *ngIf or *ngSwitch, we can opt for creating a more cleaner custom structural directive.
