Angular and React are among the most popular technologies in the sphere of front-end development. They have facilitated the work of developers, providing reusable components, refactoring, and modularization.

Angular is a product of Google, and Facebook has created React. The programs have contrasting functions and are implemented for solving diverse tasks; thus, their comparison might not be comprehensive. Users have to understand that Angular is an MVC framework and React – a front-end library with a large number of kits.

Accordingly, there are many discussions regarding the effectiveness of both approaches and whether working with mutable or immutable/unidirectional data is finer. Naturally, the mentioned web-technologies have their benefits and shortcomings, so the choice comes down to a future application’s functionality. Check the key factors influencing the outcomes of projects and inquire whether React or Angular might enhance the perspectives of one’s app.


The Task and Requirements

Before deciding between frameworks or libraries, one should find out which technology is going to be more efficient for the implementation of the desired outcome. If being oriented at the speed of development and having a limited budget – choose React. It utilizes virtual DOM, which examines the versions of HTML, evaluates its parts, comparing preceding and existing versions, and updates the fragment that is out of order. This approach allows it to accelerate the app’s performance.

Angular, in its turn, suits better for multifunctional projects with extended deadlines for technical implementation. As it applies DOM, which will be updating all the fragments until it finds the necessary tag, it might have a negative impact on the performance and other settings. Usually, Angular releases updates every six months, meaning that the developers have two release cycles to make the necessary adjustments. If you have plans to update and expand the application over time, React is superior; plus, it’s lightweight. Angular goes for heavyweight apps and provides more tools, being more complex. For the development of native apps, React utilizes React Native while Angular prefers NativeScript.


Programming Languages: TypeScript or JavaScript?

React applies JavaScript, which has dynamic typing. Such languages require less time for writing codes and offer more flexibility to the developers. From the customers’ database point of view, JavaScript has more perspectives, being much more popular among users. Nevertheless, TypeScript, utilized by Angular, is gradually improving its functions, attracting new customers. It offers optional static typing and has codes, which are simple in navigation, as well as facilitate and accelerate code refactoring.

However, it has a complicated syntax, which requires having the previous experience to work with it. In general, Angular is a more complex technology that demands an understanding of fundamental topics, like services, modules, and templates, as well as more difficult, including zones and compilations. In this regard, React has a lower barrier to learning. Moreover, the creators of React aren’t the inventors of functional programming; that is quite an old idea. However, React has clearly popularized this concept among a new generation of programmers.

In terms of data binding, these two technologies are widely divergent. Angular utilizes two-way binding between components. For example, when changing one element of the interface, the corresponding state of the model is also altering, and vice versa. React, in contrast, has one-way binding; firstly, the model state is updated, and after that, it reflects the change of the interface element. However, when altering the interface element, the model state remains the same.

A Compilation of Angular and React’s Benefits and Shortcomings

To make it easier to compare two web-technologies, it’s worth identifying their strengths and weaknesses. Also, the world’s leading companies have different preferences, choosing one technology over another. Thus, it’s useful comparing your own apps with the companies’ ones when deciding between them. React is implemented by Netflix, Instagram, the New York Times, and Whatsapp. As for Angular, its “community” is smaller; nevertheless, Apple, Nike, Xiaomi, and Grammarly favor this technology.


React’s advantages include:

  • the exceptional flexibility of an application;
  • effective utilization of Virtual DOM;
  • lightweight databases;
  • simple migration between versions;
  • allows easier browsing for search bots and improve user interaction;
  • open-source library;


As for its flaws, there are a few of them:

  • slightly chaotic documentation;
  • confusing syntax.


Chosen by many companies, Angular has the following benefits:

  • functions are interrelated;
  • a vast number of tools;
  • minimal risk of making mistakes;
  • detailed documentation allows developers to receive all the necessary information at once;
  • architecture is made for building scalable applications;
  • implementation of dependent components related to modules.


Speaking of the technology’s gaps, these are:

  • relatively slow performance;
  • Angular is difficult to master because of the variety of different structures.

Both technologies provide opportunities for creating mobile apps. Angular utilizes Ionic framework, which uses an embedded Apache Cordova. However, a produced app is a product inside the web-container. On the other hand, React Native is a platform for the development of truly native mobile applications. Despite the rapid growth of React, Angular remains a reliable and stable technology. Additionally, when developing real-time apps, like ones for chatting or working with messages – choose Angular. For cross-platform and single-page applications, flexible framework, and support and guidelines from the developers’ community – pick React. Based on the mentioned characteristics, one can decide on the preferable web-technology. The chosen framework will have a significant impact on the time you spend on programming and the project’s budget.


Thus, it’s almost impossible to say that one web-technology exceeds the other because when choosing between them, one has to rely on the project’s needs rather than the popularity of a specific technology. Angular is more suitable for companies with large teams while React is better for those who are newcomers in the front-end development. There are some tasks that can be qualitatively solved by Angular and which are neglected by React, while other objectives are more effectively addressed by React.
