πŸ“š Quick Study Guide

  • πŸ”‘ Framework Choice: React, Angular, and Vue.js are popular choices for building interactive UIs.
  • πŸ—οΈ Component-Based Architecture: These frameworks encourage building UIs as reusable components.
  • πŸ”„ 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.
  • πŸ“‘ Data Binding: Connecting your UI components to the data.
  • πŸ’Ύ Local Storage: You can save to-do items to local storage so they persist even after refreshing the page.
