Angular is a JavaScript/TypeScript framework for web development that enables the creation of Single Page Applications (SPAs). Developed by Google, Angular is a powerful, feature-rich framework that follows the MVC (Model-View-Controller) architecture.
- 🌟 Developed by Google - Backed by one of the tech giants
- 📱 Single Page Application (SPA) - Creates dynamic, responsive web apps
- 🔄 Regular Updates - Angular releases a new version every 6 months
- ⚡ Fast Performance - Optimized for speed and efficiency
- 🚀 Rapid Development - Accelerated development process
- 🎯 Component-Based Structure - Modular and reusable components
Important Note: Angular and AngularJS are different frameworks
- AngularJS (1.x) - The original JavaScript framework
- Angular (2+) - Complete rewrite using TypeScript
