Before proceeding to the comparison let’s take a quick look at the features of each of frameworks.
Google Presents: AngularJS.
Angular became popular and revolutionized the market thanks to its ability to solve many problems associated with building single page applications.
Take a look at some of the advantages of AngularJS:
- Angular directives
- On-board form validation
- Dependency injection
- A solid templating engine
- Two-way data binding
However, one of the cons of two-data binding and AngularJS is difficulties while working with large data like blocks of images or searching a heavy content. This is where React comes ahead.
AngularJS 2 has brought many new features and advantages to the framework. Continue reading to see the benefits of AngularJS.
- Decision Making - Despite having a harder learning curve, AngularJS provides a lot of new functionality and does not burden you with making decisions.
- Component structure - AngularJS 2 looks more like a platform now than a framework, and developers can easily use its components with implementing other frameworks.
- Developing environment - AngularJS development services can be done in any environment. Choose whatever you like!
- Testing in AngularJS vs. ReactJS - AngularJS was created to make testing easy, and has a major advantage in this sphere.

Now let’s take a look at the key differences of React.js that help define and differentiate the framework among competitors.
The Virtual DOM
While Angular was manipulating the DOM directly, React has a completely different approach to this question; it stores 2 copies a Virtual DOM. The first copy is the original; the second one is the updated version, which reflects the changes done from the client side. Both of these versions are run through a function called React that singles out all the differences between two versions and completes several DOM operations to modify only the fragments of the view that actually altered. This is how the magic of React is done, thus saving lots of time and resources.
Nevertheless it’s optional, and developers can choose their own style of coding. If you prefer traditional programming paradigms, let it be so!
Another feature of ReactJS that goes against newest trends in development is Server-side. While web developers prefer to leave the rendering jobs to the browser, React can be rendered both on the client and on the server, providing more flexibility in coding. Server-Side Rendering was mostly created to support the Virtual DOM and speed up all of the processes in it.
Moreover, ReactJS Native is much more focused on user interface and provides users with a highly responsive interface.
Another big difference between Angular2 and React is their size. As mentioned previously, Angular is easier to start and comes with many different implemented libraries. React needs to be filled with several add-ons before you can start working with it, anyway, even with all of the suggested libraries, React is much smaller, than AngularJS.
According to Restuta Angular’s minified version is 566K, while React with libraries is 144K.
Conclusion for the battle between AngularJS & ReactJS
When Should You Use React?
React wins when you have a lot of dynamic content and a lot of changes are to be done on the front-end. Unlike most client-side frameworks on the Internet that that struggle with rendering large data, ReactJS is at its best. This is why many dynamic websites like Facebook and Instagram choose ReactJS (Not forgetting the fact that Facebook owns Instagram and React, though).
Thanks to the amazing community of React.js developers, each day more and more add-ons and libraries are created to empower the development process. React can also be used as a library for AngularJS.
Why You Should Use Angular JS.
Lowering development time is a major struggle for both developers and businesses. It can decrease costs and help a company to grow faster. If this is what matters to you most, Angular JS is all you need.
With the release of Angular 2.0 on May 2, 2016, fans of AngularJS received another reason to love their framework even more. AngularJS 2.0 had a huge performance boost compared to its predecessor. It includes server-side rendering and now has the option to use one-way data binding as React. Now AngularJS can also manipulate only the exact parts of the DOM that need to be changed. This way Google has eliminated one of the main disadvantages of their framework. Angular 2 was more of a rework than an update. So if you are thinking of installing the 2nd generation of this framework, you will still have to learn how the new version works.
Now you surely have a much better understanding of how frameworks work and which are their pros and cons. So, here is what I would recommend about the both frameworks.
Chose ReactJS when
- You are developing a mobile application
- Your web app has lots of data
- SEO is a priority
Choose Angular as it is;
- Faster in development
- Easier to start
- Has more reliable testing
Last but not the least; let’s take a look at some of the websites that use our frameworks:
