Vue.js and React.js are two frontend JavaScript frameworks popular in the developer world, switching top spot on the podium each year in the categories of "most loved, used or popular".  Both tools offer developers a productive approach to building various Web applications, but each has its own best use cases and responds to different business needs. In this article, we’ll explore what those use cases can be, along with perks that make Vue.js and React unique.

Vue.js and React—Why They're Loved

There are many reasons for Vue’s and React’s prominence on the developer landscape, but before we dive deeper into their distinctive features, let’s briefly go over what the two share that makes them so in demand.

Virtual DOM —instead of re-rendering the whole page as is the case with regular DOM, React and Vue update only those objects that have changed, saving the time and resources that heavy DOM manipulations otherwise consume.

Component-based UI development — Vue’s and React’s considerable libraries of components facilitate code reuse, improve developer productivity, and speed up the development process.

Focus on the view library—separate concerns for routing, state management, etc.

Official component library for building mobile apps—quite long-awaited in Vue but now supported in both tools.

React and Vue Background

React was created for the purpose of targeting specific needs at Facebook, and it continues to be maintained by the tech giant. In the past there were doubts regarding React’s license; currently, however, the tool operates under the MIT License—which makes it open source.

React’s corporate backing, especially from such a major player, indicates stability in the future and implies that React will continue to be developed with long-term support.

Vue, on the other hand, was built by one developer, Evan You, in order to improve on available JS tools. A former Google employee on their Angular team, Evan You wanted to create a framework that combined the best approaches to frontend development from Angular, Ember, and React with other features that made writing Web apps faster, easier, and more pleasant.

From the get-go, Vue was a truly open source project, relying on the community, contributors, and crowdfunding to move forward.

Syntax—A Big Differentiator in React and Vue.js

One of the biggest differences between Vue and React is the way the view layer is built.

By default, Vue uses HTML templates, but there’s an option to write in JSX.

In React, on the other hand, there’s solely JSX. Vue’s traditional separation of concerns into HTML, CSS, and JS makes it easier even for beginner frontend developers to learn how to create Web applications. HTML templates are also familiar to most Web designers, and thus improve collaboration between developers and designers.

React’s JavaScript Expressions (JSX) combine HTML and CSS together into JavaScript. This XML-like syntax lets developers build self-contained UI components with view-rendering instructions included. We’ll talk about what that means later in the article.

Talent Availability and Hiring Demand

Although Vue.js is easy to learn (60% of the SoV 2021 respondents describe it this way), there are more React developers on the market who are already experienced in this framework and would use it again.

So if there is a business need for a more complex app, getting an experienced React developer who can jump into the project and start working immediately can take less time. On the other hand, the pool of Vue.js developers has been steadily growing in the last six years so this is becoming less challenging, too.

Interestingly, The Jet Brains Dev Ecosystem 2021 survey showed slightly different numbers and revealed that the developer knowledge and regular usage of the two frameworks is high, with Vue.js being on the rise. The share of Vue.js users grew from 34% in 2020 to 43% in 2021 while React experienced a drop from 64% to 49% in a YoY comparison.

We surveyed 1,500+ developers and CTOs in 2020 and 2021 and found that 90% of them plan to use Vue.js in their next projects. In 2019, 11% of the respondents had been using the framework for over two years.

In 2021,  that percentage has grown to 42,1%, showing that Vue is continuously being used within the companies. Over 55% of respondents are convinced Vue.js is going to get even more popular in their organization within the next 12 months.

How Developers Feel About React and Vue

The way professionals see React and Vue might help others decide which of the two is more suited to their current expectations and capabilities. Although there aren't available any reports asking this question anymore, answers from 2018 are rather ever-green aspects so we can treat them as up to date to huge extent. 

What devs love about Vue.js:

• Easy learning curve
• Elegant programming style and patterns
• Good documentation

What devs love about React:

• Elegant programming style and patterns
• Rich package ecosystem
• Widespread usage

React took the top spot in the most-popular web framework list in the 2021 Stack Overflow Survey, with 40.14% respondents choosing React while Vue.js went two positions up getting 5th place. Given its steadily rising popularity, we can predict its growth in the following years.

Best Use Cases of Vue vs React

Vue.js

Being a progressive framework, Vue can be integrated into an existing project incrementally, per project requirements. For example, as a lightweight library to add some interactivity to a Web application.

In fact, 75% of developers participating in the 2021 edition of the State of Vue.js Report consider ease of integration Vue’s second biggest asset. With a great documentation in hand, implementing Vue.js into a project becomes even faster.

With an easy learning curve and tools such as Vue CLI 3 and Vue UI, Vue is excellent for quick delivery of MVPs and startup ideas. Because of those, Vue is also a cost-effective solution for small to medium apps.

"Vue is the kind of library that’s incredibly flexible. It's so easy to get a quick prototype of something up and running. Yet, the moment you need to scale it to use enterprise architecture, Vue is ready for you to scale up while still ensuring you have a performant app." - Ben Hong, Vue Core Team 

Don’t let that fool you into believing Vue isn’t a good fit for large Web apps. Quite the opposite. Vue has a vast ecosystem of tools and companion libraries, allowing the framework to respond to the complex needs of enterprise-grade applications. such as:

React.js

Since React was created for large-scale Web projects, choosing it for small and simple apps might be overkill. Although it requires a lot of boilerplate code just to set up a working project, React’s architecture ultimately pays off in the long run.

JSX leaves developers the full power of JavaScript at their disposal—flow controls and advanced IDE features such as autocompletion or listing are included in the component view templates.

Unlike Vue, React doesn’t have official packages for routing or state management. To build complex apps, you have to use third-party solutions for pretty much everything. But the choice is vast. Experienced developers tasked with delivering advanced projects will know which of the numerous libraries will be the best choice to meet the business demands of a particular Web application.

Web Apps Made with Vue.js and React

Both Vue and React are used by many internationally renowned services and apps.

Here are five companies which use Vue:

It’s worth noting that React is also used in Instagram—service belonging to Facebook.

The Right Tool Depends on Your Needs

Vue.js and React are both great tools for building interactive user interfaces. To choose which one is better for your next project, you have to take a number of factors into account, including your specific use case, your business needs, environment, developer availability, budget, and the timeframe you’re working with.

Vue is lightweight, easy to learn, and pleasant to write in. Because of its familiar templating syntax and use of components, integrating or migrating existing projects to Vue is faster and smoother. For that reason, Vue.js is great for startups but can be just as well used in large-scale applications.

Performance-wise, Vue.js is on a par with React. However, final results essentially depend on optimization efforts and application size. The documentation is excellent, explaining everything in minute detail.

Vue has official packages for state management, routing, or server-side rendering, which come with up-to-date support and ensure synchronization throughout your system. With Vue CLI 3 and Vue UI, setting up a project and preparing it for deployment is lightning fast. This, in turn, helps build MVPs in a quick and efficient manner.

React, on the other hand, is a veteran of the JS field. With corporate support, a large community, and an even bigger ecosystem, React is great for building complex enterprise-grade applications. Also, the job market is booming with experienced React developers, so you won’t find yourself in short supply of specialists. Because its maturity and community, reaching out for help and getting a prompt and detailed answer is more or less guaranteed.
