10 Key React Advantages: Why Choose It for Your Next Project?

If you’re looking to create a front-end part of a web application, chances are 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 web pages to date and more than 298,000 unique domains.

There are many benefits of using ReactJS, the chief among them being the language it uses — JavaScript, which is 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 deciding to use it is an important step.

At ProCoders, we have prepared an article to help you make an informed decision.

What Is ReactJS and How Does It Work?

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

ReactJS is also helpful because 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 React’s virtual DOM that operates a bit like a “DOM tree.”

These funnels, together with faster requests enabled by the virtual DOM, aim to find the most efficient way to update the browser’s document object model. This, among many other advantages, is why so many companies trust their high-performing 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 on the server side, too.

Key Features of ReactJS

ReactJS is a powerful JavaScript library that offers a wide range of features, making it an ideal choice for building dynamic web applications with complex and dynamic interfaces. Let’s delve into some of the key features that set ReactJS apart:

Component-Based Architecture

One of the standout features of ReactJS is its component-based architecture. This approach enables developers to break down complex interfaces into smaller, reusable components. Each React component encapsulates its own structure, logic, and styling, making it easier to manage and scale React applications. This modularity not only simplifies the web development but also enhances code maintainability and reusability.

Virtual DOM

ReactJS employs a virtual DOM, which acts as an efficient intermediary between the actual DOM and the application. The DOM operates like a “DOM tree,” directing traffic and handling requests more efficiently. This results in faster rendering and updates of the browser’s DOM, significantly improving the performance of web projects. By minimizing direct manipulation of the actual DOM, ReactJS ensures smoother and quicker user interactions.

Reusable Components

ReactJS excels in promoting code reusability through its reusable components. Developers can create components once and use them throughout the application, reducing code duplication and enhancing consistency. This not only speeds up modern web development and app state management as well. In this model, there are downward data flows, which means that data flows in a single direction, making it easier to track changes and debug issues. This unidirectional flow reduces the complexity of the app development process and ensures that the application state management remains easy and predictable.

React Tools

To further streamline the development process, ReactJS provides a suite of developer tools. These tools, including the React Developer Tools and React DevTools, make it easier to debug and optimize applications. Developers can inspect the React component hierarchies as they appear in the virtual DOM, isolate specific parts of the code, and make necessary adjustments, all within a user-friendly interface.

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.

Here are some of the largest websites now running using React, also from SimilarTech:

Tip from ProCoders: There are many things that can be done with React simple chatbot is one of them! If you want to implement this technology into your project, consider React JS as a tool. You can use one of the most widely used frameworks for your web projects or React Native for developing mobile native applications (mobile app development where the product looks native but has shared code for both iOS and Android).

What Are Some Key Benefits of Using 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 key benefits of React JS, in closer detail:

1. Simplified Scripting — What Are the Advantages of Using React

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 makes your whole application run faster.

2. React’s 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 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 this function truly shines here. 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 app 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. 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. ReactJS for SEO-friendly Websites

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). 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 Instruments 

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.

React Native for Mobile App Development

While React JS is primarily seen as a web application library, it has been upgraded to support the app development of mobile applications for both iOS and Android. Thus, React Native was created.

It’s a popular tool for cross-platform development, as the code can be reused for both iOS and Android, saving time and money on React Native development. As a result, you get to create dynamic mobile native applications (well, almost native) that can accompany the scalable web applications made with React JS.

8. Easy to Learn, Easy to Use JavaScript Library

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 fold this new capability easily into your existing IT maintenance structures.

9. Rich Ecosystem and Community Support

ReactJS boasts a vast ecosystem with numerous libraries, tools, and extensions that can help streamline development processes and solve common issues.

And does ReactJS have good community support for developers? Yes, it has a robust community of developers who contribute to its continuous improvement, share knowledge, and provide support through forums, tutorials, and open-source projects. provide support through forums, tutorials, and open-source projects.

10. Flexibility and Performance Optimization

ReactJS provides developers with the flexibility to choose their architecture, tools, and libraries, allowing them to tailor their development stack to their specific project needs. Additionally, React’s ability to manage updates efficiently with its reconciliation algorithm ensures optimal performance, reducing unnecessary re-renders and enhancing the overall user experience.

Some Disadvantages of Using ReactJS

In this article, we’ve already discussed the benefits of using ReactJS. However, 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. Search Engine Optimization 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. That means you’ll need extra attention from your search engine experts to make sure that you use ReactJS for single-page applications (SPAs), in particular, with thorough testing and vetting 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 tools such as Next.js or Gatsby.js to solve the issue.

When to Use ReactJS vs. Other Frameworks Like Angular or Vue.js?

React addresses common issues with responsive and ease of use in JS libraries. It’s 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.

When Is the Use of React JS Not Beneficial?

Choosing the right framework for your project is essential. ReactJS has many benefits and is flexible enough to be useful for the majority of companies. But it’s not always an ideal 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.

React js Web Development and Maintenance Costs: What Will Your Business Gain and Lose?

React.js development and maintenance costs vary based on several factors such as location, project complexity, and experience level of the developers. ProCoders prepared a table, in which we compare the US and UK ReactJS developer’s markets with common alternatives. Let’s have a look:

Location	Talent Pool Size	Tech Universities Amount	Average Developer Monthly Rate (USD)	Developers Quality	Other Pros	Other Cons
US	Large	High	$8,000 – $12,000	Highly skilled, experienced, innovative	Strong entrepreneurial culture	High salaries, competitive job market, talent shortage
UK	Large	High	£4,500 – £8,000	Highly skilled, experienced, innovative	International talent, growing startup ecosystem, diverse economy	High salaries, competitive job market, talent shortage
Central Europe	Large	High	$2,500 – $5,000	Highly skilled, experienced, cost-effective	Well-established education system, lower cost of living, lower salaries, highly innovative and entrepreneurial	Language barriers, cultural differences
Mexico	Growing	Moderate	$1,500 – $3,000	Developing talent pool, lower cost of living	Lower salaries, proximity to the US, growing startup ecosystem	Shortage of experienced developers, uncertain political environment, cultural differences, language barriers
India	Large	High	$1,000 – $2,000	Skilled but varying quality, cost-effective	Large talent pool, lower salaries, growing startup ecosystem, highly innovative and entrepreneurial	Quality 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, and 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 the benefits of React JS and forget about pitfalls such 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 level of English and shares our values, such as honesty, work transparency, and modern corporate culture.

But let’s get back to budget calculations. Are the low maintenance costs one of the benefits of ReactJS? 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, companies such as Netflix don’t hire junior or middle-level developers, only senior developers. 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 regularly released to improve functionality and address security vulnerabilities. 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 they work and how changes will impact their 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 the developers’ skills and location. Whether junior developers are enough to provide cheap maintenance depends on the specific project and its requirements.
