In case you do not know yet, AngularJS has been developed by Google while ReactJS is a product of Facebook. Before we can go for in-depth ReactJS vs Angular comparison and decide which is better, let us look at the basic differences.
AngularJS has two-way data binding option and it automatically manages all dependencies. On the other hand, ReactJS needs additional tools to manage dependencies which is a big drawback.
Due to the presence of two-way data binding, Angular is slightly laggy in comparison to React JS. It can get slower if there are several views available that are dependent on one another. That is why React JS is preferred for SPAs with multiple views at a time. Another reason for the slow performance of Angular is that it works with real Dom and when this real DOM gets updated, the browser has to make many modifications of the internal values which is not the case with virtual DOM that React JS works with. If you are looking for high performance, React JS is a clear winner.
The first advantage of Angular is that it has a vast community support where you can get solutions to your problems quicker. The availability of full-fledged architecture makes it easy to develop complex web application conveniently.
Among the disadvantages, Angular is difficult to learn due to complex syntaxes and other complexities. The developers have to focus on the security aspect minutely as it is a client-side rendering technology. As far as the disadvantages of ReactJS go, it lacks a proper framework and one has to learn Flux for the implementation of ReactJS based view.
