AOT compilation reduces the required load time by compiling templates and components at build time, ensuring faster rendering on iOS devices. Moreover, tree shaking eliminates unused code, making applications more efficient.

2. Rich Ecosystem of Libraries

Angular’s ecosystem is vast, featuring a variety of libraries and tools that simplify the development process. From state management libraries like NgRx to UI component libraries like Angular Material, developers can leverage existing resources to enhance their applications without reinventing the wheel.

3. Code Reusability and Maintainability

As mentioned, Angular’s component-driven architecture allows for code reusability. Developers can create reusable components that can be utilized across different parts of an application or even across multiple projects. This boosts productivity and promotes adherence to DRY (Don’t Repeat Yourself) principles.

4. Strong Community Support

Angular boasts a vibrant community of developers and enthusiasts who contribute to its growth. This community support translates to abundant learning resources, tutorials, and forums for troubleshooting, making the learning curve much less steep for newcomers.

5. Seamless Integration with Ionic

Ionic is a popular framework that extends Angular to mobile app development.
