ReactJS vs AngularJS – Choose The Best Framework For Your Project

If you’re feeling torn between two of the most loved JavaScript frameworks – ReactJS and AngularJS, this post is just for you.

Choosing the right framework for your project is pivotal to its long term success and scalability. AngularJS, managed by Google has been around for a little longer than ReactJS is owned by Facebook. Both frameworks are easy to use and unique in their own ways. They are both designed to build cutting-edge mobile and web applications. Both have some compelling advantages and a few disadvantages too. This post will perform a comparison of the two, to help you assess which one is more suitable for your project.

Angular VS React

angular versus react js

JavaScript frameworks are continually developing, and as a result, frequently updated versions of Angular and ReactJS keep surfacing. If we performed a quick study of the demand represented in Google Trends for the last 5 years of Angular and ReactJS, we can see that the two are almost equally preferred, except a few variances. Check out the graph below. The blue and red lines represent Angular, and React.

You can see that both the frameworks have been more or less equally adopted, with Angular leading for some time and React catching up later.

Angular is a MVVM framework built on Typescript, founded in 2009, for building highly interactive web applications. It comes with a complete suite of developer tools and well-integrated libraries and features that help developers build high performance scalable web apps. Angular has the support of tech giant Google, and comes out with regular updates that make it cutting edge technology. That is why Angular is currently being used in 345,348 websites and 170,380 unique domains.

In fact, Angular has come a long way since it started out, and supports diverse functionalities today. It is one of the most preferred frameworks among seasoned developers, when it comes to enterprise grade app development like single page apps or progressive web apps.

So if you want apps that pack in high functionality and dynamic data while staying light in its bones, Angular makes for a great choice. Let’s take a look at some of the biggest Angular benefits for web app development.

Top Benefits of Angular:

Angular offers new features like enhanced RXJS, really fast compilation (in under 3 seconds), and a new HttpClient launch. Thanks to its detailed documentation that allows effective communication and collaboration between developers, Angular makes development easier and faster. Some of the top advantages of using Angular for app development are:

Two-way data binding

Angular features two-way data binding that enables automatic synchronization to minimize risks of possible errors. When data is changed or modified, two-way data binding enables the Model and View to be updated simultaneously, making all modifications real-time, tus producing more accurate results and quicker development times.

MVVM (Model-View-ViewModel) Architecture

MVVM simplifies development and allows developers to work separately on the same app section using the same set of data. the framework isolates business logic from the UI components, thereby facilitating clean design and smooth operation.

Dependency injection

Thanks to Angular’s Pain Old Javascript Objects (POJO) model, the code structure becomes handy and independent of external dependencies. Developers are saved from having to add complex functions in the programme and hence requires less coding.

Optimized server communication

Angular creates static files and also reduces the response time to API calls, significantly lowering the burden on CPU. This makes caching super-simple with Angular.

Code Consistency

Code consistency is the key to a successful development environment. The Angular CLI and comprehensive ocumentation style guide makes consistency a star in Angular. The Angular CLI tools allow developers to create projects, run tests and various features keeping the entire team on the same page.

Ivy Renderer

The next generation Ivy renderer enhances performance, loading speed, and dynamic loading of components. It provides unparalleled code debugging and also reduces file sizes making the framework accessible and feature-rich.

Drawbacks of Angular:

The complex syntax that comes from the first version of Angular was a difficulty. Nevertheless, Angular 5 uses TypeScript 2.4 which is the least difficult to learn in comparison. Migration issues which can appear while moving from the older version to the latest ones can be sometimes troublesome.

Companies that use Angular 5: Upwork, Freelancer, Udemy, YouTube, Paypal, Nike, Google, Telegram, Weather, iStockphoto, AWS, Crunchbase.


ReactJS is an open-source JavaScript library, created by Facebook in 2013, used for frontend UI development. Engineers at Facebook were just trying to build a dynamic and high performance UI to optimize their internal development needs, and React.js was born. React.js is a declarative, flexible and efficient JavaScript library specifically responsible for building a hierarchy of UI components for web applications. It uses reusable components to render views, allowing developers to reduce build time for their web apps. It helps manipulate the website DOM faster using the virtual DOM model. Essentially, it is the V part of MVC architecture – helping you develop the View layer of web applications. It helps build web applications faster with rich UI and reusable components.

React.js provides support for both frontend and server-side. It is used by all kinds of businesses – small to large – to build single-page applications and mobile web apps. Some of the biggest examples of companies using React.js are Facebook and Instagram.

Benefits of ReactJS:

Easy to learn.

React is extremely easy to learn because of its simplified syntax. With their HTML writing skills, developers can easily write in React. There is no need to learn TypeScript deeply like in Angular, making the learning curve a lot gentler for new and transitioning developers.

Virtual DOM (document object model)

React’s Virtual DOM allows arranging documents in HTML, XHTML, or XML formats that are better accepted by web browsers while parsing different elements of the web app. That combined with ES6/7, ReactJS can work with heavy loads with relative ease. It’s downward data binding enables data flow that prevents child elements from affecting parent data. Apps built with React JS are extremely lightweight because the data performing on the user side can be easily represented on the server side simultaneously.

Incredibly Fast Web Applications

This one’s a fun backstory. Facebook was only looking for a way to reduce the Facebook application build time, or re-build time to be specific. They weren’t exactly going after partial refresh of the virtual-DOM. Yet they discovered that a partial refresh was making the application much faster than the conventional full refresh.

The React virtual DOM model refreshes only parts of the page, making is significantly faster than the DOM full refresh. React knows just when to re-render a part of the application by observing data changes to the state.

The result is incredible speed in your web applications built with react.

Component Based Architecture

React introduced the idea of component based architecture and reusable components. This allows React.js developers to take individual pieces of UI elements that work like Lego blocks that can be combined to form a complete, independent, sustainable micro-system.

These components can be mixed and matched to form different applications or parts there-of. So every time you develop an application, the components save you the trouble of writing extensive boilerplate code. Just grab the components you need and build a UI you want in very little time.

SEO Friendly Applications

Since React.js renders on the server-side, it gives your applications or webpages an edge with search engine optimization, bringing in ample organic traffic. With server-side rendering, the Google bots visiting the server see the indexed and cached content. Also as the page load time decreases, that’s an extra boost to the SEO. Overall, your webpages come into higher visibility and scale the rankings with minimal effort.

Drawbacks of ReactJS:


React.js can run a little high on the overhead costs. Sometimes, the need arises to download additional react libraries which can cost time and money.

Learning Curve

React.js tends to have a steeper learning curve than React Native. New developers may need to spend some time learning React.js before they can proceed to development.

External library support

There are very few native libraries for react and a high dependency on third-party libraries. The third-party library ecosystem is vast and well supported though, but it can be time consuming as well as involve a learning curve.

Long data navigation

Data navigation with react can be long and complex. Unlike other JS tools, React doesn’t support parallel data handling and navigating the data hierarchy requires cumbersome effort.

Companies that use ReactJS: Facebook, Instagram, Netflix, New York Times, Yahoo, Khan Academy, Whatsapp, Codecademy, Dropbox, Airbnb, Asana, Atlassian, Intercom, Microsoft.
