• Learn about how Angular utilizes TypeScript and its advantages in building scalable applications.

Components and Data Binding:

• Explore different types of data binding in Angular (one-way, two-way).
• Learn how to create and manage components effectively.
• Understand how to use decorators like @Input, @Output, and @ViewChild.

Directives:

• Master Angular's built-in directives like *ngIf, *ngFor, and ngSwitch.
• Understand how to create custom directives to manipulate DOM elements and behaviors.

Services and Dependency Injection:

• Get a deep understanding of Angular services and how they are used for sharing logic across components.
• Explore dependency injection (DI) patterns in Angular and how to provide services at the correct scope.

Routing and Navigation:

• Learn how Angular's router works, including route configurations, lazy loading, route guards, and navigating between views.
• Explore the concept of child routes and dynamic parameters in routing.

Forms in Angular:

• Differentiate between reactive forms and template-driven forms.
• Learn how to handle form validation, dynamic form fields, and form submission.

RxJS and Observables:

• Understand the power of observables in Angular and how to integrate RxJS for managing asynchronous data streams.
• Learn about operators like map, filter, mergeMap, and switchMap for handling complex data transformations.

State Management:

• Learn how to manage state within Angular applications using services or state management libraries like NgRx or Akita.
• Explore how to implement a store pattern and handle side effects.

Performance Optimization:

• Discover techniques to optimize Angular applications for performance, such as change detection strategies, OnPush, and lazy loading of modules.
• Learn how to optimize large-scale applications using trackBy, async pipe, and efficient change detection mechanisms.

Unit Testing and Debugging:

• Understand how to write unit tests for components, services, and pipes using Jasmine and Karma.
• Explore debugging techniques for Angular applications using Chrome DevTools and Angular-specific tools.

Advanced Angular Concepts:

• Dive into topics such as custom pipes, dynamic component loading, and Angular Universal for server-side rendering (SSR).
• Learn how to leverage Angular’s AOT (Ahead of Time) compilation and Ivy rendering engine for efficient builds.

Angular CLI and Tooling:

• Master the use of Angular CLI for scaffolding, building, testing, and deploying Angular applications.
• Learn how to set up development environments, manage configurations, and work with tools like Webpack and Docker.
