React vs. Angular: Who Wins the Competition?

Choosing the Best Option for Front-End Development

React.js vs. Angular. They are equally good at building web-based applications. Some of the world’s projects are built with React.js, others of the same size, with Angular.

These examples emphasizing both React.js and Angular are suited for making large and scalable platforms, handling massive requests per moment.

Current Statistics by Popularity

React.js gets on the top position and overruns Angular with the number of Node Package Manager (NPM) downloads on GitHub. The difference is huge.

Last year’s survey among Stackoverflow’s users demonstrates that React.js is 10% more popular than Angular.

React.js More Popular Than Angular

Does it mean that something goes wrong with Angular? Or, does it imply React.js offered better solutions than Angular?

Main Principles of Angular

Let’s figure it out by overviewing both systems in a nutshell. Angular originates from the startup products of Google, where the key of product development was to manage multiple processes in one place. Any unreasonable decision could lead to a problem and affect billions of user operations run in a moment.

Angular became a monolithic framework that predefined programming steps. Even though it enriches the development process with the services, controllers, and modules, it dictates its own way of thinking and working. That places a distance between programmer and framework.

Along with that, there are a few other factors that make Angular less accessible: 

  1. Angular uses object-oriented programming (OOP), so its knowledge is hard-skill.
  2. Developers should have a good command of TypeScript.
  3. Knowledge of RxJS is a must-have too.

Apparently, the learning curve is very high. Unlike React.js, Angular demands more OOP-related experience from developers. That worked for Google, considering their team’s high expertise. Angular was envisioned as an end-to-end solution and was compatible with their advanced programming culture.

Despite the complexity of the architecture, Angular has its indisputable benefits:

  • Two-way data binding automates synchronization between the Model and the View. Say, if the data was changed in the Model, it would be changed automatically in the View (DOM). Such a function takes off the need to write more additional code. Just imagine Google Drive’s document, as a user types text in the document, it is viewed by another one in real-time. Such a function is possible due to the two-way data binding.
  • Dependency injection (DI), makes it possible to deliver the dependency from one to another class. Due to DI, server-side services could be delegated to a client-side. So, it is a serious advantage of OOP usage in Angular.
  • Directives aimed to enrich the HTML by providing a new syntax to it. The most common directive is the component. Using it, programmers could create any attribute for an existing element and change its behavior. This is a helpful feature, which makes working with the DOM very flexible.

Angular is enriched with many other valuable features, like UI Material, making it possible to reuse the code of components in other parts of the project, but this is similar to what React offers too.

Who Chooses Angular Today?

Experienced front-end developers share that Angular fits well with enterprise solutions and the corporate sector when React.js is a better choice for early-stage startups and smaller companies. This could be explained that big business does not change their priorities very often and the strategic goals are known to their CTOs far earlier.

The main point you could take from our overview is to remember that Angular is a better option for long-term projects requiring reliability above anything else. Besides others mentioned in the list, a few more companies are using Angular: Microsoft Office, Deutsche Bank, and Samsung.

React.js even doesn’t call itself a framework but a JS library. Unlike Angular, React.js makes it a developer’s responsibility to set a project structure, find relevant services for HTTP routing, and so on. At this point, React’s ideology is to be agile and provide developers with absolute freedom. As a result, it leads to minimizing the project’s size from start, as they could involve those libraries that they need by a certain time.

Let’s imagine that you are the only front-end developer on the project, or there are just a few. The main goals are set for the shortest perspective here. You should be both fast and productive, be able to adjust to startup goals. The straight rules and architecture demands of Angular will slow down the process of development.

So, following single policies is not a major priority for the React.js community. In fact, this is straight opposite to Angular.

It is worth mentioning, React.js couldn’t work alone, as it is only the View (V) and needs an engine for data processing. A developer needs to figure out its implementation, manage with Redux and Saga, and arrange that individually.

What makes React.js Different?

  • The learning curve is low. A developer with HTML and JavaScript experience could take on web development and show their first outcomes soon.
  • The architecture is simple and doesn’t take much time to study all its structure.
  • Virtual DOM made server-side rendering less time-consuming.
  • Huge community support that regularly contributes to React.js collection.
  • Intuitive environment, pleasant interface to work with.

What problem does virtual DOM solve?

The current situation is next: if anything has been changed in a user browser while clicking on a page, these changes will be automatically recorded to the DOM. To show the changes on the web page, the browser should reload the entire DOM structure. It brings more loads to the browser and slows down the performance of the application.

React.js Innovations in Performance

  • React.js creates a snapshot of the DOM, which is named the virtual DOM (VDOM).
  • Every new change in the UI component is to be recorded to the new virtual DOM first, not the regular one.
  • React.js compares the new version of the VDOM and determines if those changes were essential to update the browser’s DOM.
  • If the changes were essential, React.js updates the DOM with the latest portion of changes.

React.js has such computing algorithms that allow it to decide when to update the DOM in the browser. That makes front-end applications very performative. Unlucky, Angular doesn’t have anything similar to this feature.

React.JS Approach in HTML RenderingWith that said, React.js helps to write clean JavaScript code for the projects when Angular complements the HTML with many extensions. This becomes messy in a while and hard to deal with such an enlarged code.

It is time to say: React.js dominates in the front-end development area today.

Advanced features, ease of use, extensive collection of javascript libraries placed React.js in a higher position than Angular. That proves an idea that the user-centered approach is a king. React.js has become an intuitive and powerful resource for making front-end applications.

The discussions like ‘Angular vs. React’ are obviously coming to an end because of the React.js win. Nowadays, the community is much interested in other frameworks like Vue.js, and comparison of that kind will be more actual today.
