    Description

    Introduction of Angular Components and Modules

    Welcome to “Understanding Angular Components and Modules”! This training will provide an in-depth exploration of two fundamental building blocks in Angular: components and modules. You’ll gain a clear understanding of how components and modules work, how to create and use them, and how they interact within an Angular application. This course is designed for developers who want to deepen their understanding of Angular architecture and improve their ability to build scalable and maintainable Angular applications.

    Prerequisites

    Before starting this training, you should have:

    1. Basic knowledge of HTML, CSS, and JavaScript.
    2. Familiarity with basic programming concepts (variables, loops, functions, etc.).
    3. A foundational understanding of Angular (e.g., familiarity with basic Angular setup and usage).
