1) Data Binding
If you want a true MVC framework, then data binding is a must. And if that’s what you need, Angular is perfect for you. Data binding enables us to control how our UI changes when our model changes.
The beauty of angularjs development service directives is that they encapsulate all of our code into a single unit that can be easily replicated or reused. From here, we have two methods at our disposal: compile and link. Compiling a directive allows us to simply specify a DOM element and transform it into a component using template expressions. On the other hand, linking gives us more control over when and where we want to inject content from.
3) Dependency Injection
Angular relies on Dependency Injection (DI) extensively. This is a design pattern in which one object creates and passes another object its dependencies (usually other objects) upon request, rather than having one object instantiate or construct other objects itself. Dependency injection helps keep your code decoupled, which is important in large projects with lots of developers working on different parts of an application simultaneously.
Writing quality tests is one of most important parts of developing web applications with any framework. The two most popular frameworks, Angular and React, are both very test-friendly. They have their own testing frameworks, but you can also use whatever testing framework works best for you or is recommended by your team. Testing gives you assurance that what you’re building is working properly now and will continue to work as new features are added in later on.
