What is React JS

When it comes to frontend engineering, selecting the best solution is essential. Whatever your business goals are, you need to make sure that the tools you choose are going to help not hinder you. 

Making sure that your front-end is engaging and intuitive will ensure you create a great first impression and make it lasting, too. The key to creating a strong frontend is choosing the best tech solutions, but with so many options available, this can feel like a bit of a minefield.

One great option for your business is ReactJS (also known as React or React.js), an incredibly popular tool used the world over by some of the world’s most influential companies. You may have already heard of ReactJS, but what are the benefits of selecting it for frontend engineering? In this article we breakdown exactly what ReactJS is, and the top reasons you should consider choosing it for your next project.

What is ReactJS?

ReactJS is an incredibly popular front-end JavaScript library that’s already being used by some of the most powerful global brands like Tesla, NASA and Netflix. It’s maintained by Meta (formerly Facebook) and is an efficient and flexible tool for building intuitive and scalable products. 

With ReactJS, you’ll be able to create User Interfaces (UI). Great UI not only looks pretty, it’s intuitive and allows customers to navigate your product easily, while keeping them engaged. 

Benefits of React JS

When it comes to developers building UIs, ReactJS helps to minimise bugs that can occur by using components. React components are modules that allow developers to make simple adjustments to certain aspects of the code, without affecting the whole solution – think of them as the building blocks.

The result of using components is that the code is much more stable, meaning a properly functioning product with far less bugs. In addition to this, ReactJS’s ecosystem is also full of ready-made components which can be personalised and used in one’s own projects. 

5 reasons why you should choose ReactJS

So, you understand what ReactJS is, but why is it the best choice for your next project? The main benefits of React JS development can be broken down as:

5 benefits of React JS: effective UI, speed, flexibility, stability, scalability

Now, let’s explore that list in a bit more detail…

Effective user interfaces

ReactJS has user interface at its core. Because it is declarative, it allows developers to create interactive and dynamic UI faster and in an organised manner. When developers make changes to the data, ReactJS will update and take care of the rendering, making it painless to create great UIs.

ReactJS is declarative, so it allows for creating interactive and dynamic UI faster and easier.

ReactJS, when compared to other libraries and frontend development frameworks, renders much faster. This means that your product will load quickly for users. Not only does this provide them with a better, more seamless experience, it also helps with your SEO. Pages and applications with faster load and rendering speeds are much more likely to rank highly on Google.

Speed icon


ReactJS allows developers to easily recycle components multiple times, instead of writing the code from scratch for the same features every time. Developers can use ReactJS libraries to look for and select code that has already been built by other developers. This saves a lot of time and means your product will be delivered quickly. It will also help you make quick updates to your project’s look and feel when you need it. 

With ReactJS, developers can easily recycle components, which saves a lot of time on developing features.

When creating new products, developers need to make time to properly test the UI to make sure everything is running as it should be. Traditional UI testing can be a hassle for developers to set up and can be very slow.

However, ReactJS is simple to set up and allows components to be tested quickly. Developers are also able to run different tests at the same time. This means you’ll be able to get a quality product that has been tried, tested up and is running fast.

Flexibility icon


As mentioned above, this framework works with a React component-based structure, in which the components act as building blocks for your application. This has a number of benefits as it allows for a lot of flexibility. 

ReactJS is also very flexible because it can be used with a variety of different tools. You can use ReactJS to create static websites, build mobile apps and even create desktop applications. Additionally, it’s constantly evolving to support new use cases every day.

Stability icon


Compared to other frameworks, ReactJS is notable for its very stable API that rarely changes, which makes app maintenance that much easier. The code is therefore much more stable and is less likely to cause bugs.

Not only does this make developers’ jobs much easier, but it also ensures that your product will run smoothly. A properly running app means an enjoyable and engaging experience for your customers.

Scalability icon


Stable code that allows developers to make individual changes without altering the overall structure means that ReactJS is suitable for projects that will scale in the future. Developers will be able to change elements as your needs evolve. Because ReactJS works with a huge number of development tools that serve different purposes, you’ll be able to scale your app in whatever direction you need to.

ReactJS works with lots of different development tools, enabling to scale projects in an easy and flexible way.

One such example is ReactJS Dev Tools. It provides a minimum set of tools for anyone to start with and create a basic project, and as the project becomes bigger, other more complex tools – such as Redux Dev Tools – are available to use and expand it further.

Summary: Getting started with ReactJS

Now you know the ins and outs of ReactJS and how it can benefit your business. It’s an excellent tool that can be used no matter what your industry is. Trusted and used by Facebook, Amazon, Uber and more, you can be sure that you’re making a safe choice with ReactJS.
