11 min.

If you’re looking to create a front-end part of web application, the chances are good that ReactJS is a programming tool that’s been recommended to you. But is it the right option for your project? For thousands of businesses, that answer has been yes. In fact, according to the latest report from SimilarTech, ReactJS has been used on more than one million websites to date and more than 298,000 unique domains.

Industry verticals where React JS is being used

There are many benefits of using ReactJS, the chief among them being the language it uses — JavaScript, what’s arguably the world’s most popular programming language. Because of this, ReactJS is easy to use, generally easy to learn, and improves your web applications’ performance and interoperability.

When it comes to the pros and cons of ReactJS, there’s a lot to love about what it can do for your code. But making the decision to use it is a big one. At ProCoders we prepared an article, that will help you walk through it.

What is ReactJS?

ReactJS was created by Jordan Walke, an engineer at Facebook, in 2011. Its purpose was to be an open-source JavaScript library to facilitate front-end web application development. At the time, Facebook’s engineers needed a JavaScript-enabled library that would allow them to run multiple user interfaces at once, like chat and news feed updates, for instance.

Walke addressed this by merging XHP, Facebook’s markup syntax, into JavaScript. As a result, ReactNative was born, and Facebook had a front-end library that allowed them to run and manage their user interfaces and front-end web applications.

When the powers to be at Facebook saw how well the library worked, they soon made it an open-source offering in 2013. Since then, it’s become one of the world’s most beloved and frequently used JavaScript library programs, so a lot of super React website examples have been developed.

This recent Angular vs. React vs. Vue vs. Svelte comparison by Stack Overflow shows that it’s currently number one among its competitor programs. With the library’s huge community of users and Facebook’s help in backing and maintaining it, the whole programming world is beginning to appreciate the advantages of using ReactJS.

How Does ReactJS Work?

ReactJS is lightweight, creating a JavaScript library that accelerates UI development with shortcut paths and reusable UI components. React JS can manage the view layer of all your front-end web applications and mobile apps.

ReactJS is also helpful because of how it speeds up the (DOM) Document Object Model in the application programming interface (API). The React library defines a logical structure for all the documents used in the application through the use of a virtual DOM that operates a bit like a “DOM tree.”

These funnels, along with requests faster as the virtual DOM, tries to find the most efficient way to update the browser’s DOM. This, among many other advantages, is why so many companies trust their web applications to ReactJS. React was designed to be used in the browser, but with the addition of NodeJS, its DOM trees can be used server-side, too.

Projects and Companies that Use React JS

ReactJS is popular globally, but by far, it has the most usage in two of the world’s largest population centers — The United States and China. This analysis by SimilarTech below shows how many websites in each country have websites built with React.

8 Main Advantages of ReactJS

When it comes to evaluating the pros and cons of using ReactJS, most programmers quickly find that the advantages outweigh the disadvantages. Let’s take a look at the advantages of React JS, in closer detail:

1. Simplified Scripting  

React JS features a free syntax extension called JSX. This makes your HTML markup within the library much easier. Its writing shortcuts allow you to make your course code simpler and cleaner, converting your HTML mockups into ReactElement trees. JSX not only helps avert code injections, but it makes your whole application run faster.

2. Component-based architecture

One of the key ReactJS advantages is its modular design. React.js uses a component-based architecture that allows developers to create reusable components for the user interface. This makes it easier to maintain and scale applications. 

3. Faster rendering 

Earlier in this article, this library’s Virtual DOM was mentioned, and here is where this function truly shines. React’s “tree” model means that a problem at the top of the tree can cascade throughout the tree. To solve this problem, the Facebook development team created the Virtual DOM, which directs traffic and requests more efficiently. In any consideration of React.js advantages and disadvantages, this is a clear game point for the library. It provides key speed and accuracy for high-volume apps.

4. Stable Code Structure 

Again, this is an area where the library’s “tree” function comes into play. In React, the data flows from the top to the bottom of the tree. And this has an enormously stabilizing effect on your code. Small changes or bugs in the “child” structure don’t affect the “parent” code. This type of data binding leads to code that’s more stable and faster running. When evaluating the pros and cons of using ReactJS, this is an important “pro” to remember.

5. SEO-enabled 

Have you ever searched for something on Google or another search engine, like “best pizza near me,” and noticed how some websites show up at the top of the search results while others are buried on page 10? That’s because the websites at the top of the search results have better search engine optimization (SEO). And one of the major React JS benefits is that it can help make your site SEO-friendly with the help of server-side rendering, dynamic rendering, and meta tags.

6. Handy developer tools 

Editing React code has become even easier with developer tools designed as a dev extension in Chrome and Firefox. This allows programmers to inspect the React component hierarchies as they appear in the virtual DOM. You can also isolate certain parts of your code and edit them accordingly.

7. Mobile app development 

While React JS is primarily seen as a web application library, it has been upgraded so the framework works for developing mobile native applications for both iOS and Android. In this case, great app performance is another advantage of React JS.

8. Easy to Learn, Easy to Use 

Most programmers with a good grasp of JavaScript can learn to React within a few days. And in consideration of ReactJS advantages and disadvantages, this one is a game point to JS. Its widespread use means you can cast a wider net for your development talent and find more qualified candidates.

But also, if you turn over a completed application from your development team to your general IT maintenance staff, you are far more likely to be able to easily fold this new capability into your existing IT maintenance structures.

Some disadvantages of using ReactJS

In this article, we’ve already discussed the benefits of using ReactJS. But any thorough understanding can only come from a discussion of React JS pros and cons. There are plenty of downsides in any debate about React advantages and disadvantages, as it’s not for every project or organization. We’ll break it down here. (And if you’re considering moving from JavaScript to TypeScript, our article might help).

1. The pace of Development 

React is a fast-moving, fast-changing library. Updates are made every few months, and new programming wisdom bubbles up from reacts enormous community on a near-daily basis. This can be difficult to keep up with for some programmers.

However, as a technology, react has been around for enough years to be a fairly mature library and comfortable development environment. There are far fewer changes, as the core of this offering has stabilized. 

2. Poor documentation 

Because the entire React ecosystem is changing so quickly, new tools are coming out so fast, and the documentation often doesn’t come out fast enough to keep up. This can be an advantage or disadvantage of ReactJS, depending on how you look at it. This can be a significant disadvantage and one you have to weigh against the React benefits. But many find they can get around any glitches by employing other solutions like Redux and GraphQL.

3. SEO can still be tricky 

React JS has proven that it often mitigates the difficulties that Google has in reading JavaScript. But it’s not perfect. And that means you’ll need extra attention from your SEO experts to make sure that your single-page applications, in particular, are thoroughly tested and vetted against Google’s search algorithms. In fairness, every SPA has this SEO issue.

In fact, SEO experts recommend running your apps through the Google Search Console tools, so you can see firsthand how well your apps are interacting with the search engine. In the end, programmers can use such tools as Next.js or Gatsby.js to solve the issue.

In What Cases Will ReactJS Be the Best Solution?

ReactJS is a responsive, streamlined, easy-to-use JS library that is great for organizations large and small. It’s user-friendly and comes ready to scale for organizations that run lots of user-facing functions in a high-traffic environment. It’s a great library to use if you have a website that needs to run simultaneous functions, and the basic nature of the language sets you up easily for changes in the future. If you think you can stay within the ReactJS sphere for the long term, this library is a good play.

What Projects Shouldn’t ReactJS Be Used For?

ReactJS has many benefits and is flexible enough to be useful for the majority of companies. But it’s not always the right choice. For instance, if you have a very small project, or want to create a static website, React.js can be overkill. Simpler libraries or frameworks may be a better choice, as they can be easier and faster to set up and use.

React.js also may not be the best choice for applications that require extremely low latency or real-time performance. Other technologies, such as WebSockets, may be better suited for this.

IndiaLargeHigh$1,000 – $2,000Skilled but varying quality, cost-effectiveLarge talent pool, lower salaries, growing startup ecosystem, highly innovative and entrepreneurialQuality can vary widely, cultural differences, potential communication challenges

As you can see, while the rates for React.js development in the USA and the UK are high, and the market here experiences a shortage of ReactJS developers, businesses can still get quality work done at a lower cost by working with developers in Central Europe. These countries (Portugal, Estonia, Croatia, Albania) have a highly skilled pool of developers who are able to provide top-quality work at a lower cost.

And if you work with a reliable outstaffing partner such as ProCoders, you can take advantage of all benefits of React JS, and forget about such pitfalls as language barriers and cultural differences. We always pay extra attention to communication with our clients in order to create a smooth development process. Every employee in our company has a great English level and shares our values, such as honesty, work transparency, and modern corporate culture.

But let’s get back to budget calculations. Is the low maintenance costs one of the ReactJS benefits? Well, it depends. Some of the most significant factors include:

  • The complexity of the application: The more complex an application is, the more time-consuming and expensive it is to maintain. For example, such companies as Netflix doesn’t hire junior or middle-level developers, only seniors. Due to that, the cost of maintenance can skyrocket quickly. 
  • Frequency of updates: One of the React JS advantages is that it is an evolving technology, and updates are released regularly to improve functionality and address security vulnerabilities. But on the other hand, it means, that it may require more maintenance, which can increase costs.
  • Level of documentation: Applications with poor documentation may require more time for developers to understand how it works and how changes will impact its functionality. And time is money.

All in all, the costs of development and maintenance for React.js projects vary depending on several factors, including the complexity of the application or website, the team size, and developers’ skills and location. Whether junior developers are enough to provide cheap maintenance depends on the specific project and its requirements.

Why is React JS so popular?

Numerous React.js benefits are what make it so popular. Component-based architecture, high performance, large developer community, cross-platform compatibility, and backing by Facebook – this is only the tip of the iceberg.

Is ReactJS good for large applications?

Yes, React.js is well-suited for building large applications. Its component-based architecture and efficient rendering engine make it easier to manage and scale large codebases. Additionally, React.js provides tools and libraries, such as Redux, that can help developers manage application state and improve code organization.
