React JS and is it worth creating projects

React JS is a JS library used to create user interfaces. Meta created it and is used in many major apps.

One of the key features of React is that it uses the concept of components to create interfaces. Components are independent blocks of code that can be reused and combined to create more complex interfaces. Each component has its own state and behavior, which can be controlled through props. Note that it is better to seek React JS consulting for a successful project.

React also uses a virtual DOM (Document Object Model) that allows you to optimize performance when updating an interface. Instead of updating the real DOM with each change, React updates only the necessary parts of the virtual DOM and then compares it to the real DOM to determine which parts should be updated.

React can also be used with other libraries and frameworks such as Redux, React Router, Next.js, and many others to create more complex web apps.

What is React JS consulting?

It is a consulting service provided by companies and experts. Consultants help you use technology in the most effective way, solve problems, and get the most out of this library.
Consulting services can include:

  • Code analysis to identify potential problems and improve performance.
  • Project design and architecture.
  • Evaluating and improving web app performance.
  • Training and coaching.
  • Assistance in selecting and integrating tools and libraries.
  • Creation of user interfaces (UI) and interactions with APIs and backend.

Consulting can be useful for teams and projects of any level of complexity, from small websites to large scale apps. It helps improve quality and efficiency and achieve better results in a shorter time.

Is consulting a necessity?

Consulting can be helpful, especially if the team doesn’t have enough experience with the library. Here are a few reasons consulting may be necessary:

  • Efficient use: the platform is a very flexible and powerful library, but using it in the most efficient way can be difficult for newcomers. A consultant can help you use the library in the most effective way by providing tips and best practices, as well as help in determining the best approach to solving specific problems.
  • Defining the project architecture: React JS provides a flexible framework, but correctly defining the project architecture can be challenging for new teams. A consultant can help determine the right project architecture, given the specific needs and requirements of the project.
  • Performance optimization: can be very fast and productive, but improper use of the library can lead to performance issues. A consultant can help optimize performance using best practices and tools.
  • Mentoring and coaching: Consulting can also include training and coaching to help improve their performance skills. The consultant can help address the team’s knowledge bottlenecks and provide guidance on how to improve their performance.

In general, it is not mandatory, but it can be very useful for teams who want to use the library in the most efficient way and achieve maximum results in their projects.

How to choose the right development company?

There are several key factors to consider when choosing one:

  • Experience and knowledge: Check the experience and knowledge. Make sure they have experience with the library and check that they’re using best practices and the latest versions of the technology.
  • Reputation: Check the reputation. Read client testimonials and examine the portfolio to see what projects they’ve already done and what level of quality they provide.
  • Team: Make sure the company has a team of experienced professionals who can work effectively with React JS. Check that they are using best practices and technology to provide the quality and efficiency of the work.
  • Price: Cost can be a key factor in choosing a company. Compare the prices of several companies to find the best value for money.
  • Communication: Communication is key. Make sure the company has good communication skills and is willing to keep you informed of the process.
  • Timing: Determine how quickly you need the project done, and make sure the company can complete the project within the specified time frame.
  • Choosing a company can be difficult, but if you consider these key factors, you can find the company that is best suited for your project.

The process of developing in React JS from scratch

The process usually involves several steps, such as consultation, development, testing, and deployment. Let’s take a closer look at each stage:


Consultation with the client and determine the basic requirements and goals of the project. At this stage, details such as functionality, design, performance requirements, and other factors that may affect the project are clarified. Key performance indicators (KPIs) and project success metrics are also defined at this point.


At this stage, the project structure is created and code writing begins. Developers use React JS to create components and bind them together into a cohesive system. They can also use libraries and frameworks to speed up implementation.


When the code is written, there comes the testing phase. Professionals test the operation of components and the system as a whole to make sure everything is functioning properly. At this point, code debugging and bug fixing are done.


After the successful completion of testing, developers deploy the app to a live server. Additional tweaks and configurations may be made at this point to ensure maximum performance.

Support and upgrades

After launch, maintenance and support must continue. This may include bug fixes, functionality updates, and performance improvements.

The result is a powerful and fast product that can be used for a wide range of tasks across industries.


Why is React JS gaining popularity every year?

The popularity of the technology is growing every year for several reasons:

  • High performance: provides high performance through efficient state management, virtual DOM, and multithreading.
  • Large community: has one of the largest communities. This means that there are many libraries, utilities, and tools to help speed things up and solve different problems.
  • Scalability: this allows you to make scalable web apps that can handle large amounts of data and users.
  • Code reuse: provides the ability to reuse code by using components that can be reused.
  • Cross-platform: can be used for web development, on mobile platforms, and even for desktop apps using Electron.
  • Convenience: provides a simple and easy-to-use syntax.

React JS is a highly attractive tool for developers looking to create efficient, fast, and scalable web and mobile applications. Its ability to render UI changes efficiently using a virtual DOM, scalability through the use of reusable components, and the ease of integration with other technologies, makes React JS a popular choice among developers. These advantages make React JS an excellent choice for businesses and individuals seeking to build products that are both productive and scalable, ultimately leading to a better user experience for end-users.
