Angular or React: What should you choose for the next application?
Published: 2019-09-09 15:48:58

Frontend and web app development is one of the most popular directions in the software development world, and one of the most rapidly developing spheres in the IT sector.

What is the first technology that comes to your mind when you think about Frontend development? Most likely the answer is JavaScript - one of the leading programming languages on the IT-market today. JavaScript has always been one of the most loved technologies among web developers and, since it has so many admirers, no wonder that IT-enthusiasts all over the world has created so many JS-based tools, frameworks and libraries to optimize the language, and make the web development coding experience smoother and less headache-causing.

Today we would like to talk about the 2 perhaps most popular JS-based technologies for creating interfaces - React and Angular. There are tons of requests on Google considering which is the best option for frontend development nowadays. First of all, let’s start with the fact that comparing React and Angular is a little bit unfair, since React is a library, while Angular is a full-fledged framework. However these are both significant technologies  among providers of [ web application development services](https://smartym.pro/web-application-development/). 

Anyway, the question is still open, so let’s find out which one is better to utilize in your next web project. So, [React](https://en.wikipedia.org/wiki/React_(web_framework)) is a library (!) for building user interfaces, released in 2013 by Facebook; Angular, on the other side, is a framework, released 3 years later in 2016 by Google. [Angular](https://angular.io/) is written in TypeScript (which, in its turn, is based on JavaScript), and is nothing but a complete rewrite of the older AngularJS that was released in 2010. 

__Demand and popularity__

Let’s compare the demand on the market for the React and Angular developers, using the statistics on the number of published vacancies on 5 popular international resources: LinkedIn, Indeed, Dice, AngelList and SimplyHired.

As you can see, the gap between React and Angular is not that significant. The website “The state of JavaScript”, based on its own research, made a conclusion about the Angular’s fall for the last 2 years.

And now let’s look at what people think  based on several information resources:

- NPMtrends data show that over the last 2 years the number of React’s downloads has increased by almost 10 times, while the same digit for Angular has increased only by 4 times;

- React has almost three times more stars on GitHub than Angular, and a lot more contributors;

- According to a survey, held by a popular developers resource StackOverflow, React is the second most loved framework (in case you’re interested, a Python-based TensorFlow took the 1st place), and Angular is the 4th hated framework (after Cordova, Xamarin and Hadoop), and also React is the leading technology that IT-enthusiasts want to learn;

- There is almost an equal amount of Google requests considering React and Angular.

We can make a conclusion, that Angular development is not really wanted among real people that use it in their work, while React is much more warmly welcomed among web developers.

__Programming experience__

_Performance._
First of all, React uses Virtual DOM (Document Object Model), Angular utilizes Regular DOM. What does it mean? It means, that React wins, because having a Virtual DOM helps a lot to improve the overall  speed, performance of an application and the user’s experience. However, this is relevant only for huge systems that deals with hundreds of data requests per one page. In smaller applications it doesn’t almost make any difference;

_Library vs Framework._
The fact that one of these web application development technologies is a library, and another is a framework implies tangible differences. Angular as a framework has a strict structure and rules, however, being a framework also means that Angular gives more functionality opportunities out-of-box, which can’t be said about React since it is a library. For example, with React you can’t work properly with state management, for this you need to add another library, e.g. Redux or  MobX. Or, to process http-requests you will either need to go native using JavaScript or ask for help from an instrument called Axios. With Angular, all of the above can be easily done from within the framework itself without any 3rd-party libraries, other frameworks, etc.;

_Freedom and creativity._
Nevertheless, although Angular gives you more functional opportunities, it gives you less freedom and agility in ways to implement this functionality, which is a complete vice versa in case of using React. And it actually is a double-edged sword. Yes, React gives you more space for creativity, but the more extravagant you get with React, the more easily things can go wrong. Just for example, if you use independent libraries along with React, you have to take care of all the updates for each of them, and nobody can guarantee you complete interoperability. Angular, on the other hand, has very little flexibility, so you have to stick to its rules;

_Best for new-comers._
The Angular’s learning curve is much steeper, since it is written in TypeScript, which is a statically typed language. The entry barrier to Angular’s world is higher, since there are hundreds of concepts to learn. However, once you’ve learned it, you will have more knowledge and a complete full-fledged framework’s powers on your side. JavaScript, that React is based on, on the contrary, is a dynamically typed language, it is much easier to learn. Moreover, dynamically typed languages require less time to write code and, again, provide web developers with more freedom. Anyway, React is much better for newbies;

_Stability._
Experienced Angular developers complain that the framework is changing too much, forcing to review and rewrite almost the whole code nearly every six months. Consequently, Angular past knowledge simply becomes irrelevant. Every update is dreaded by developers, because they have no idea what major changes are coming next;

_Mobile development opportunities._
Probably you all heard about React Native - a React-based framework that enables to create amazing mobile apps both for iOS and Android, almost indistinguishable from native applications. React Native has made a great name and gained a lot of popularity over the last couple of years. By the way, if you are interested in learning more about cross-platform mobile app development with React Native, we have an article [here](https://medium.com/@smartym.pro/react-native-vs-ios-android-native-what-is-the-best-choice-for-mobile-development-today-67cde42fc8bc). And what about Angular? Well...there is a “nice” thing called Ionic - a framework based on Cordova, and, if you have been reading our article attentively, you should remember that Cordova is the most hated framework ever :) I guess, no more explanations needed.

__Conclusion__

Finally, we would like to point out that the technology you choose will mostly influence the speed of the web application development process. Both Angular and React have their own peculiarities that you should take into consideration when choosing a technology for a web project. The main points of the article are:

- React is just a small library, Angular is a full MVC (Model-View-Controller) framework (while React give you only “V” out of MVC);
- React gives good performance indicators due to its Virtual DOM;
- React is better for beginners, but Angular gives more skills;
- React has greater mobile solutions;
- Both are easily scalable;
- React has a bigger community and is more welcome among developers;
- React works faster than Angular.

To be precise, there is no right or wrong decision. In our opinion, the choice mainly depends on the time you have for creating a project. If you want to save time, use React; if you don’t want to risk failing due to extensive amount of creativity and too many other libraries and frameworks in your project - take the strict and fully-equipped Angular.
