About the Technology

Whether you're building lightweight web clients or full-featured SPAs, Angular is a liberating experience for developers used to other web frameworks. Angular feels like a natural extension to HTML, so you don't feel like you're constantly context-switching as you build up your applications. Angular's declarative style makes it easy to define and add features without dozens of lines of manually written boilerplate, and the fully integrated TypeScript language gives you the benefits of a statically typed language within the JavaScript ecosystem. Plus, adding Angular and TypeScript to your resume makes you a hot commodity. Learn Angular, and your apps will be better, you'll be more productive, and you'll be in demand too!
