Angular Installation (CLI)

Welcome to our Angular Tutorial! Today, we'll guide you through the process of installing Angular using the Command Line Interface (CLI). Let's dive in! 🎯

What is Angular?

Angular is a powerful open-source framework for building dynamic web applications. It is maintained by Google and a community of individuals and companies.

Why use Angular?

1. Reusable Components: Angular allows you to build applications using reusable components, which makes your code more organized and easier to maintain.
2. Two-Way Data Binding: Angular automatically updates the view when the data changes and updates the data when the user interacts with the view.
3. Dependency Injection: Angular uses dependency injection to manage the dependencies between different parts of your application.
