Frontend frameworks focus on the user interface and user experience. They help in building a responsive, dynamic, and interactive client-side of the web application. **When to Choose**: - If your project is heavily focused on the client-side, for example, a dynamic web application with real-time interactions and animations. - When you want to improve the look and feel of your web application, making it more engaging and responsive to user actions. **Examples:** 1. [[React.js]] (most popular). See [[Integrating Django & React.js]]. 2. **Angular.js:** developed by Google; a comprehensive MVC framework that includes a wide range of built-in features, from a template engine to sophisticated state management. Its two-way data binding ensures that model state changes automatically align with any changes in the UI, and vice versa, but it can be more complex to learn, especially for beginners. 3. **Vue.js:** developed by Evan You to address shortcomings of Angular.js; is a progressive JavaScript framework that is designed to be incrementally adoptable, offering a simpler and more flexible API compared to Angular.js. It also uses a virtual DOM and provides features like two-way data binding, making it a good choice for developers at all levels, particularly beginners. 4. [[Anvil.works]] In summary, React.js is great for fast, interactive UIs and has a large community, but requires additional libraries for complete front-end solutions. Angular.js is robust and feature-rich, ideal for large-scale applications, but has a steeper learning curve. Vue.js, on the other hand, strikes a balance between the two, offering flexibility and ease of use, making it suitable for a wide range of projects. See [[UI Component Library]]
