I've been watching videos and reading articles but this specific article make me so confused, at the start of the article it says
The applications in Angular follow modular structure. The Angular apps will contain many modules, each dedicated to the single purpose. Typically module is a cohesive group of code which is integrated with the other modules to run your Angular apps.
A module exports some classes, function and values from its code. The Component is a fundamental block of Angular and multiple components will make up your application.
A module can be a library for another module. For instance, the angular2/core library which is a primary Angular library module will be imported by another component.
Are they exchangeable terms? Is a component a module? But not viceversa?
Components control views (html). They also communicate with other components and services to bring functionality to your app.
Modules consist of one or more components. They do not control any html. Your modules declare which components can be used by components belonging to other modules, which classes will be injected by the dependency injector and which component gets bootstrapped. Modules allow you to manage your components to bring modularity to your app.
