Generators are these magical functions that you pause and resume, whenever you want — they don’t execute continuously.

Let’s list out the benefit of standalone functions:

-- Decouple tight dependency between the component and the store.
-- Simplifies CRUD operation with the store, by providing simple interfaces for the component to use to interact with the store.
-- Reusability!
-- No need to create a service(facade) to encapsulate NgRx logic.
-- Stand alone functions are not tied to a class, meaning each can be imported and used individually.
-- Reduces the need to inject multiple facade dependencies.

There are different types of API protocols:

REST — relies on a client/server approach that separates the front and back ends of the API and provides considerable flexibility in development and implementation.
RPC — The remote procedural call (RPC) protocol sends multiple parameters and receives results.
SOAP — Supports a wide range of communication protocols found across the internet, such as HTTP, SMTP, and TCP.
WebSocket — Provides a way to exchange data between browser and server via a persistent connection.

MIME (Multipurpose Internet Mail Extensions) types are used to identify the type of content delivered in a file. MIME type validators, in the context of Angular, are functions or classes that verify whether a file’s MIME type matches the expected type.

The primary purpose of MIME type validation is to verify that the content of a file aligns with the expected format. This is especially crucial when dealing with sensitive file types, such as images, where incorrect MIME types could lead to rendering issues or security vulnerabilities.
