React Vs Angular: 5 Most Important Differences You Must Know

React and Angular are currently two of the most famous names in web development and technology. But since they are both so popular, it is often hard to decide which one you should go for. We will discuss the five most important differences between React and Angular that will help you decide which one is better for you.

But before we start off with the fun stuff, let’s take a quick overview of what these two are for people who are new or unfamiliar with their concepts:

React is a Facebook-supported JavaScript library, and it became open-source in 2013. Since then, it is pretty popular as component-based architecture in the web development industry. It is incredibly popular among developers for its components, ease in mobile development, and simple maintenance. On the other hand, Angular is a Google-developed web framework that was released in 2010. Ever since then, it has been a popular, well-loved web framework, mainly because of its dependency injection and two-way data binding features.

Now that we know what they are, let’s take a look at the most important differences between them.

  1. React Is Much Safer Than Angular

Security is one thing you don’t want to compromise on when you’re choosing anything tech-related and React is known to be a lot safer than Angular. Where did this evaluation come from? It’s simple: when we compare the security issues found in projects that were either Angular-based or React-based, their severity scores gave us an overall idea of the risk posed in both these options. Apart from that, CVSS (The Common Vulnerability Scoring System) is another significant criterion that helps us get an idea of how vulnerable a framework is.

CVSS efficiently translates numerical scores and turns them into ranges classified by the severity type. For example, the severity of 0.1 to 3.9 is classified as low. Similarly, severity numbers 4.0 to 6.9 are medium, and 7.0 to 10.00 are classified as high risk. When the CVSS results of Angular and React were compared, it was evident that the vulnerabilities were lower in React than in Angular. These results were observed and compared over the years and the scores for React started with a 7.1 in December of 2013. They became 6.5 in March of 2015 and remained 6.5 in August of 2018. Angular, however, had far higher vulnerability scores in 2013 as well as 2018. These scores decreased as the framework matured, but it still poses a higher risk than React.

2. Easier To Learn

The learning curves of these two programming frameworks are very different. Angular is much harder to learn and has a lot of syntax and concepts to engulf. In comparison, React is much simpler and has an easier learning curve. Since React is easier to learn, the ramp-up time is shorter, and it doesn’t take long for the user to get the hang of it. It allows you to generate a stronger opinion about how you want to organise your code. The faster the user can learn how to use the framework, the quicker they can get comfortable. As a result, they can get better results faster. For this reason, React is also fun to work with. So, developers often lean towards it since it’s not as dull as the other framework.

Angular is also not that hard once you get the hang of it. Programmers with experience in languages like Java, C#, or C ++ might have more fun with Angular than React since they have a syntax similar to Typescript. Even if you are not very familiar with them, it only demands practice and experience to learn how to use them. However, when the user compares the learning curves of the two, Angular can be a little intimidating. Its documentation is a lengthy process, and the ramp-up time is pretty long, as well. When a framework is hard to get used to, it can take a while for it to generate results. For people who don’t want to wait that long and don’t have that kind of patience, it’s always a better option to go for something simpler. And in this case, that’s React.

3. Fastest Performance

Angular has been known to have slow performance. It works on an incremental DOM (Document Object Model), and when it creates a new DOM, it does by comparing it with the previous DOM and applies the various differences to the new real DOM while only allocating the memory if it is necessary. Because of this and bidirectional data binding processes, Angular is relatively slower. On the other hand, the star of the show is React, with faster performance and virtual DOM. React works by changing the DOM with a new virtual one and comparing it with the previous DOM, it modifies the real DOM only where the differences lie. This way, it does not overload your browser, and the unidirectional data binding process significantly lowers your workload.

There are speculations that Angular might get better over time as the technology improves. In fact, the current changes, updates, and innovations in Angular are raising the bar for this framework. It is making React and Angular easily compatible in terms of performance. However, so far, Angular is not winning, and it doesn’t look like it will any time soon. Because of these differences in performance, the market demand for React is much higher. Due to the increased popularity, it has become a preference for consumers. And with growing usage, React is taking faster measures to improve over time. It is implementing efficient solutions and improvements very quickly, making sure that it climbs the ladder faster as competitors try to match its performance level.

4. Mobile-Friendly

About ten years ago, smartphones took the spotlight, and suddenly everything revolved around them. When mobile applications, websites, and social media emerged, there was a great need to make everything fit in a small screen responsive UI. Technology companies and developers needed something that would allow them to make everything mobile-friendly but still use languages and technology that they were already familiar with. Frameworks like React and Angular make code reusability easier between mobile and web applications. Plus, they offer incredible run time performance, just like native applications. Both React and Angular feature frameworks for cross-platform mobile applications, and are pretty practical. But if they’re both usable, what’s the difference?

React has a much more efficient cross-platform mobile framework solution than Angular; the latter doesn’t offer official mobile application development support. Even though NativeScript and Ionic are the most popular platforms for building mobile applications on Angular, it still fails compared to React, which offers an official framework for this purpose. React Native is a framework hosted by Facebook, and it takes all the attention! Its performance is highly comparable to native applications and lies very close to its efficiency. Add that to the fact that it has an easier learning curve, and you’ve got yourself everything you’re looking for in a JavaScript library!

5. State Management Libraries

Both Angular and React have different features and different purposes. However, React depends on a state management library, unlike Angular, which doesn’t require any additional tools. Libraries like React Router, Redux, and Helmet can efficiently optimise state management, routing, and API interaction processes. Indeed, ReactJS is a very powerful front-end JavaScript library, but if one wants to build incredible applications, you need to incorporate different tools to amp up your game. In contrast, Angular integrates many different functions, including component-based routing, project generation, and data binding, and all of this is included in the package. However, if you wish, you can also use RxJS and NgRx to further improve all the different features.


Those were the five major differences between Angular and React, the two most popular names among developers right now. So, which one should you choose? That is still your call. Using all of this information, you can decide for yourself which one seems better for you. In the end, it is always important to remember that both of them have different features and different purposes. And your final decision should be based on which one of these serves to your requirements best. If React fits your needs and sounds like a better idea, go for it. If Angular sounds more appealing, choose that. Whichever one you choose depends on your personal needs and preferences.
