With so many JavaScript frameworks available for server-side and client-side rendering, choosing the right framework for a new project is a difficult task be it a JavaScript system, application or website. Picking a wrong framework affects project’s resilience and ability to meet deadlines.

JavaScript power contest: bare figures

The number of JavaScript tools is gradually on a rise, turning the choice of fitting technology into a contest. The problem is Angular vs React are both quite capable, modern, and extensively used JavaScript Frameworks. According to the State of JavaScript, a web portal that surveys developers; In 2017 they surveyed 20, 000 developers, while React and Angular are equally popular javacripts frameworks, React leads when it comes to developers’ adoption to the framework.

Developers’ adoption and acceptance

Out of 20, 000 developers surveyed, 14, 000 developers while only 4, 700 developers said they use and will continue to use, React and Angular respectively, in the future. 7, 600 developers said they are uninterested in Angular despite of being aware of its popularity while none of the developers said they are uninterested in React.

Moreover, all developers were either interested or were using React. The rest of them were either learning or willing to. Unlike Angular, nobody showed their reluctance towards React.

The ultimate comparison chart

Before I go any further, let me clear a few things. Although both maintained by Google, Angular 2 is separate project from AngularJS or Angular 1 and each has different repository and account on GitHub. Angular 2 uses TypeScript and renders Client-side while Angular 1 uses JavaScript and is server-side.

React, on the other hand, is maintained by Google’s biggest competitor, Facebook. React lacks a native architecture unlike Angular’s MVC and resorts to one-way data binding.

Which is more popular?

While AngularJS was extremely popular till 2016, it is losing it popularity exponentially while ReactJS is gaining considerably that today they are equal on popularity quotient if we look at Stack Overflow Trends.

Stack Overflow Trends are based on Stack Overflow’s tag. A tag can represent a programming language, technology, framework, tool or a library. A tag is popular or not based on the number of searches made on that regard.

Google Trends show a similar picture although AngularJS is still the king when it comes to JavaScript frameworks. ReactJS is catching fast.

2018 is considered by many as the year of React after it took over Angular in 2017.

If you remember GitHub gives star to each project. So I went through respective page on GitHub and found React leads in popularity here too.

React has 92, 454 stars and 5, 691 view while Angular has only 58, 215 and 4, 368 stars and view respectively on GitHub.

Advantages of AngularJS

If we consider the community support as one of the factors, no other JavaScript Framework can beat it. Developers and designers continually work together and back to the community, growing reliability and consistency of the framework.

It is a complete framework that runs in any browser environment regardless of the platform. Besides, it is reliable, includes off-the-rack tools, ng components are robust and quite evolved in juxtapose with React.

Bi-directional data binding is perhaps the key feature, as it disperses the influence after each set of data change and does away with the necessity for additional effort with data sync in model and view.

Advantages of ReactJS

JSX is a JavaScript syntax that permits HTML codes and practice of HTML tag syntax for the rendering of subcomponents. It endorses development of machine-readable programs and delivers ability to compound components in a single compile-time tested file.

Prompt rendering is one of the the top features of React that gives it a substantial edge over Angular. The technology includes shrewd approaches to lessen the sum of DOM operations, enhance and hasten the process of updates. Virtual DOM (Document Object Model) is of use while managing massive databases.

The fundamental difference between ReactJS and AngularJS is this that React is JavaScript-based while ng2 is superset of Hypertext Markup Language (HTML). JavaScript is a superior programming language to HTML, which makes React a priority when it comes simple, intensive and dependable programming.

Disadvantages of AngularJS

Notwithstanding to an all-inclusive, clear manual and extensive documentation, steep learning curve and complication are called amongst the key limitations of Angular.js. As with another client-side rendering tech in JavaScript framework evaluation list, computer programmers should give distinct importance on safekeeping of apps. The introduction of Angular Universal and pre-rendering selection in ng2 this problem was addressed–another reason for growing popularity of AngularJS.

Disadvantages of ReactJS

When we put react vs angular in juxtapose in terms of performance of the web application running on them, before anything it’s worth citing that ReactJS is more of an evolved JavaScript library that can act as a framework, not a complete framework like AngularJS and, thus, combination of the UI library into a joint MVC framework involves deeper development skills. Angular is still evolving, young and immature considering tutorial dimensions and an incomplete ecosystem.

Apart from challenges and limitations of ReactJS, it is worth mentioning Flux which is regularly applied for adding a structure and architecture to the web apps. Using either of the technologies is still a contest for inexperienced developers because of its lack of a proper structured and complete documentation.


React and Angular provides entirely varied methods to web application development for startups, SMBs and small and medium enterprises (SMEs). Both technologies are prevailing and adaptable, while neither of them is good or bad, popular or not. At the end of the day, it depends upon custom app objectives and specific system limitations, programmers can run from ng2 to React, and back.
