Exploring Modules
Explore the concept of Angular modules and their role in organizing and sharing code within an application. This lesson explains the structure of the root app module, the use of declarations, imports, and exports, and how modules enhance scalability and feature separation in Angular projects.
We'll cover the following...

const foo = 5;

export { chocolate };

Angular’s module system is much more comprehensive because it allows you to isolate, export, and group code by feature.
The app module
By default, every project you work on will have a root module. The root module is what will ...
