JavaScript Framework Examples: Build a Simple To-Do List

📚 Quick Study Guide

• 🔑 Framework Choice: React, Angular, and Vue.js are popular choices for building interactive UIs.
• 🏗️ Component-Based Architecture: These frameworks encourage building UIs as reusable components.
• 🔄 State Management: Managing data (the to-do items) efficiently is key. Consider using React's `useState` hook.
• ✨ Event Handling: JavaScript frameworks make it easier to handle user interactions like adding or deleting items.
• 🎨 Virtual DOM: React and Vue.js use a virtual DOM to optimize updates to the actual DOM, improving performance.
• 📡 Data Binding: Connecting your UI components to the data.
• 💾 Local Storage: You can save to-do items to local storage so they persist even after refreshing the page.
