Back when AngularJS was at its peak, I worked extensively with it to build dynamic, single-page applications. Its two-way data binding and dependency injection made development faster and more intuitive. I leveraged directives and services to create reusable components, improving maintainability and scalability. Back then, I navigated challenges like performance optimization with digest cycles and best practices for structuring large-scale applications. While modern frameworks have taken over, my experience with AngularJS provided a strong foundation in reactive programming and component-based architecture, which continues to influence my work with newer technologies.
