React is built and maintained by Facebook. It is quite popular in today's world and has a large community.
React follows the component-based architecture, which means dividing the application into small encapsulated parts and using them to create more complex user interfaces. This approach helps in maintainability, reusability, and optimization of the code.
Moreover, React.js works through the virtual DOM, which means that instead of manipulating the browser's DOM directly, it creates a virtual DOM in memory and makes the necessary manipulation there before updating the DOM, thus providing better performance.
Two-Way Data Binding
It uses MVC architecture, thus providing separation of concerns in your application. Moreover, it has two-way data binding, meaning that any change in the model gets reflected in the view and vice versa. Due to two-way data binding, you can easily manipulate DOM. React, on the other hand, allows one-way data binding, which means the UI components cannot change without updating the corresponding model state.
Dependency injection is one of the top features of AngularJS. It is a software design pattern in which objects are passed as dependencies in your components, and thus we do not need to hard code them, making our components reusable and maintainable.
AngularJS was designed in such a way so that it becomes testable. The entire framework is testable. We can perform unit testing for controllers or perform testing from the user’s perspective.
Ease of Learning
Node.js is best for building real-time data-driven, I/O bound single-page applications, for example, live chats, and audio and video conferencing, etc.
Node.js is not recommended for CPU-intensive applications. As the load on the CPU increases, its efficiency decreases.
