It can be seen from the chart that during the 2013–2014 there was a small difference between the number of React and Angular inquiries. Then, we see that deviation between them increased for some short period. From the middle of 2016, these requests balanced and React started to grow and reach to Angular demand closer. The Vue.js framework was still not popular very much, but it was slightly increasing its presence on the market of frameworks, showing a potential for the further growth. In the last years, Angular and React almost balanced meaning that they are most usable frontend frameworks on the market.
Overall, React and Angular develop organically with the relatively the same dynamics. If we try to forecast the demand for these frontend frameworks, then we can see a positive tendency for React while Angular has a bit of declining one. Vue.js is still not clear, but according to its specific convenient structure, it’s going to grow as well, maybe just a bit less than main frameworks.
Also, we analyzed the number of open positions worldwide that require a specific knowledge of a certain framework. As a source, we took Indeed.com and got the following distribution according to more than 60,000 job offers.
Pros and cons of Angular 5
Benefits of Angular 5:
New features like enhanced RXJS, faster compilation (in under 3 seconds), new HttpClient launch.
Detailed documentation that allows getting all necessary information for the individual developer without asking his colleagues.
However, this requires more time for education.
Two-way data binding that enables singular behavior for the app which minimized risks of possible errors.
MVVM (Model-View-ViewModel) that allows developers to work separately on the same app section using the same set of data.
Dependency injection of the features related to the components with modules and modularity in general.
Drawbacks of Angular 5:
The complex syntax that comes from the first version of Angular. 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.
Pros and cons of ReactJS
Benefits of ReactJS:
Easy to learn. React is much easier to learn because of its simplicity in terms of syntax. Engineers just need to recall their HTML writing skills and that’s it. No need to deeply learn TypeScript like in Angular.
High level of flexibility and maximum of responsiveness.
Virtual DOM (document object model) that allows arranging documents in HTML, XHTML, or XML formats into a tree from which is better acceptable by web browsers while parsing different elements of the web app.
Downward data binding which means that with this kind of data flow the child elements cannot affect parent data.
Absolutely light-weighted because the data performing on the user side can be easily represented on the server side simultaneously.
Migrating between versions is generally very easy, with Facebook providing “codemods” to automate much of the process.
Drawbacks of ReactJS:
Lack of official documentation — super-fast development of ReactJS leaves no place for the proper documentation which is a bit chaotic now as many developers contribute it individually without any systematic approach;
React is unopinionated — meaning that developers sometimes have too much choice;
Long time to master which means that React JS requires deep knowledge of how to integrate user interface into MVC framework.
Pros and cons of Vue.js
Benefits of Vue.js:
Empowered HTML. This means that Vue.js has many similar characteristics with Angular and this can help to optimize HTML blocks handling with a usage of different components.
Adaptability. It provides a rapid switching period from other frameworks to Vue.js because of the similarity with Angular and React in terms of design and architecture.
Awesome integration. Vue.js can be used for both building single-page applications and more difficult web interfaces of apps. The main thing is that smaller interactive parts can be easily integrated into the existing infrastructure with no negative effect on the entire system.
Large scaling. Vue.js can help to develop pretty large reusable templates that can be made with no extra time allocated for that according to its simple structure.
Tiny size. Vue.js can weight around 20KB keeping its speed and flexibility that allows reaching much better performance in comparison to other frameworks.
Drawbacks of Vue.js:
Lack of resources. Vue.js still has a pretty small market share in comparison with React or Angular, which means that knowledge sharing in this framework is still in the beginning phase.
Risk of over flexibility. Sometimes, Vue.js might have issues while integrating into huge projects and there is still no experience with possible solutions, but they will definitely come soon.
Chinese background. As far as Vue.js has a bit of Chinese background, a lot of elements and descriptions are still available in Chinese. This leads to a partial complexity on some stages of development, nevertheless, more and more materials are being translated into English.
