A Bold difference between the AngularJS & ReactJS:
On the grounds of performance, AngularJS fails miserably as they called on each render. It is, however, possible to use BehaviorSubject from RsJS, as it serves the purpose. React allows the use of @computed from MobX – achieving the same objective but with a nicer API.
Well, ReactJS is quite simple and easy to understand, it might take some time to launch the program in the ReactJS but it is for the developer to learn as compared to AngularJS. On the other hand, AngularJS is not at all easy to learn. Its inherent complexity sometimes causes confusion and Angular-specific 3rd party libraries and syntax.
AngularJS model doesn’t allow to add big model due to the copy-n-compare. The developer needs to break-down each coding in the AngularJS. There is no such issue in the ReactJS, in it, the ability of the developer decides the performance of websites.
AngularJS: Youtube, Vevo, Freelancer, Istockphoto, Weather, Sky Store.
ReactJS: Facebook, Instagram, Khan Academy, New York Times, Airbnb, Flipkart, Sony Lifelog.
