In this blog, we will take into account some crucial factors while discussing the difference between AngularJS and ReactJS to help you choose your project’s better fit.

React has managed to increase its popularity with its primary advantage, i.e., virtual DOM implementation which allows its libraries to render only actually changed components instead of rendering unnecessary operations and thus save time.
AngularJS vs. ReactJS: Differences between a framework and a library
Let’s put a quick glance on the image below showing some important features distinguishing AngularJS and ReactJS:
AngularJS is a mature, consistent and full-fledged framework with the ability to run in any platform or browser. It allows developers to implement efficient codes in far less time.
However, the performance of a huge AngularJS app is often slowed down by bi-directional data binding. Unlike ReactJS, each binding in AngularJS is assigned a watcher to track changes and each loop continues till all the values associated with the watchers are checked.
ReactJS, on the other hand, stands out with one of its best features, that is, prompt rendering. Its Virtual DOM minimizes the unnecessary DOM operations while optimizing and accelerating the update process. Thus, ReactJS with its smart methods becomes a preferable choice for handling vast databases.
AngularJS is more complex than React and the learning concepts associated with this framework takes more time. In addition to the complicated features embedded within the core of framework, there are a lot of unnecessary syntax and intricate component management.
However, setting up a project could be time consuming due to lack of predefined project structure. Moreover, you would need to gain an understanding of Redux library, keep up with frequent updates besides learning the best practices in ReactJS.
One of the greatest advantages of AngularJS rests on the fact that it supports dependency injection – the software design pattern that allows making components reusable, maintainable and testable.
Unlike AngularJS, a built-in container for dependency injection is missing in ReactJS and thus it has a global state for all components. However, ReactJS offers dependency injection without a container, thanks to JSX which offers the basic features of dependency injection container.
Data binding is all about data synchronization between Model and View. AngularJS offers bidirectional data-binding and mutable data which is easier to work with.
However, it has a downside, that is, it affects the performance of AngularJS apps negatively as already mentioned in the performance section.
ReactJS, on the other hand, needs Redux for allowing you to work with immutable data and makes the data flow unidirectional. This one-way data binding not only helps to control the complexity in applications but also facilitates the debugging process.
AngularJS has a large number of features and options which enables developers to implement the framework directly and easily.
On the contrary, ReactJS requires external components to render those same set of features. This will not only involve extra coding to call APIs but also need to add unidirectional data flows to manage the modules.
Directives and templates
AngularJS offers three layers – Model, View, and Controller. Shyam Sheshadri, the CEO and Co-founder of Re-Stok, defines the three layers of AngularJS in his book, AngularJS: Up and Running: Enhanced Productivity with Structured Web Apps as follows:
The model is the data, the view is the UI, and the controller is the business logic.
The JSX offers every single thing needed for development within one structure, thus allowing you to write your codes easily and compile them better.

AngularJS was created by two developers, Misko Hevery and Adam Abrons in 2009 as a side project. Currently, it is maintained by Google and a community of active individuals.
Take a quick glance on the image below to check out which companies are actively using AngularJS:
ReactJS is one of the most popular JS technologies used worldwide, and the community supporting and developing it is huge.
You would need to be a continuous learner in order to keep up with the recent updates of this JS library for it is constantly evolving.

AngularJS vs. ReactJS: Who’s the winner?
The simple answer to this question is “it depends”! It depends on your project requirements and the objectives you want to achieve through a particular technology.
Then you would need to align those requirements with the features that these technologies, we are discussing in this article, offer.
Looking for a holistic framework that will get you started quickly? In other words, seeking a robust and well-maintained framework? Also a steep learning curve is not an issue for you, so choose AngularJS for your project.
If you have any plan of expanding the functionalities of your application in the future or you need an app that will update the look with dynamic content, then ReactJS is the best fit for your project.
