JavaScript Framework Quiz: Test Your Knowledge

📚 Quick Study Guide

• ⚛️ React: A JavaScript library for building user interfaces. Uses a component-based architecture and a virtual DOM for efficient updates.
• 🟢 Angular: A comprehensive framework developed by Google for building complex web applications. Utilizes TypeScript and provides features like dependency injection and data binding.
• ⚡ Vue.js: A progressive framework for building user interfaces. Known for its simplicity and ease of integration into existing projects.
• 📦 Component-Based Architecture: Dividing the UI into reusable and independent components.
• 🔄 Virtual DOM: A lightweight copy of the actual DOM, allowing for efficient updates by minimizing direct manipulations to the real DOM.
• 🧱 Data Binding: Automatically synchronizing data between the model and the view.
• ⚙️ Dependency Injection: A design pattern that allows for loose coupling of components by providing dependencies to components rather than having them create their own.
