When comparing the popular JavaScript frameworks for a project, the most frequently picked are Angular, React, and Vue. Each one of them is having its own strengths, and it ultimately depends on the needs of your project. Let’s break their comparison into small easy-to-understand parts such as their popularity, performance, learning difficulty, and companies using them.

Angular vs React vs Vue: Quick Overview

• Angular: This is a full-fledged framework and is developed by Google. The framework contains a lot of built-in tools, but really not child’s play to learn it. Big companies are its major users because they require building huge applications which automatically access much functionality.
• React: Developed by Facebook, It is not exactly a full-fledged framework but a library used in building user interfaces. It focuses on reusable components, which saves time while building big applications. It is highly flexible, though the developers might have to make use of other tools in order to handle things that react does not cover out of the box.
• Vue: Vue is developed by a developer named Evan You. Vue is light in weight and easy to learn. Vue is normally used in smaller applications; however, it can be used for big applications also.

React vs Vue vs Angular Popularity

With a summary of each technology above, we will now be able to understand which is most popular among developers and businesses on the following basis.

• Community Size and Adoption: Generally, React is the most used of all the frameworks in both, small and large companies. It entered the market very early and has a big community that means it has abundant resources and support for its developers. Vue is new but has been growing very fast, especially in startups and smaller projects, as it’s pretty easy to learn. Angular remains popular in large companies in need of systematic and very complex applications, especially in sectors like banking and government.
• Job Market Demand: React rules the job market because of its versatility as it can be used in a wide range of industries. Vue.js is gradually being adopted, commonly among startups, while Angular is still popular for enterprise-level applications in industries such as fintech, and e-commerce, especially in the growing market like India.​

Angular vs React vs Vue Performance

Now, having a clearer picture of their popularity, let’s see how they perform in different use cases.

• Rendering Speed: Both React and Vue use something called a “virtual DOM,” which makes them quicker to update the pages. This makes it especially good for applications that have to render new texts or images on the screen more often, such as in real-time updates. Angular uses the “real DOM,” which is slower, especially if the app has much going on at once.​

• Bundle Size: The size of the file(bundle) makes a difference when an application loads within the browser. Angular has the biggest bundle size, so it can be rather slow to load. Vue has the smallest file size and is quick to load. React has a bundle size between the others two.

• Use Case Performance: If one is building something fast and interactive, an online store for instance, React or Vue would do the trick. For instance, Flipkart uses React because of its performance on updating things fast. On the other hand, if you are building some really big and complex thing, like a government portal or a company’s internal tool, Angular would be better as it already has more inbuilt features.

Learning Curve and Developer Experience – Angular vs React vs Vue

Having covered the performance aspect, let’s now see how easy it is to learn and work with these frameworks.

• Angular: Angular is difficult to learn, especially with the fact that it uses a more complicated language called TypeScript. But once learned, many of its features can easily be used to speed up web development in large applications.

• React: React is easier to learn than Angular and has a lot of helpful resources. However, because it does not come with all features needed to build an app, developers must pick and choose extra tools. This makes it more flexible but also has the downside as more learning will be required to understand the extra tools. Also, we will have to figure out how to integrate those tools with the react.

• Vue: Vue is probably the easiest to learn of the three. It’s simple but good for small projects and can also be scaled up for larger ones. So in that respect it’s ideal for developers who want to get started quickly​.​

Top Companies Using Angular, React, and Vue

Having already established the learning curves, let us consider the big giants resting on these frameworks.

• Top Companies Using Angular: Angular is used by mega companies like Google, Microsoft, and IBM. These companies take on a structured approach and build highly complex applications that require scalabilities.
• Top Companies Using React: Some of the giants using React are from Facebook, Netflix, and Airbnb. It is famed for great performance and scalability; hence, it is thus perfectly suited for applications that contain a hefty amount of dynamic content.
• Top Companies Using Vue: The framework though still young is utilized by companies like Alibaba, Xiaomi and GitLab. It is primarily responsible for the creation of extremely easy-to-use and quick-loading apps.

Conclusion

In brief, we have evidence that each framework stands out in different fields:
React is useful for apps that need to load fast and update frequently even with small startups or large companies.

Vue is best when you are after something simple and fast to learn, great for small to medium-sized apps.

Angular is for enterprise-level complex applications, especially when one needs to have a full-featured framework including everything in it.

Each framework has its own benefit; the choice would depend on the size of your project, the skills of the members
