Why choose ReactJS?

React, also known as React.js or React JS, is a free and open source front-end JavaScript library for building user interfaces based on UI React components. The software is maintained by Facebook, now called Meta, and a growing community of developers and companies. Developers use React as a base in the build of single-page, mobile, or a server-rendered web application with frameworks like Next.js.

ReactJS is versatile, flexible, easy-to-use and efficient for delivering a scalable front-end project for both web and mobile apps. It allows developers to build intuitive, engaging applications quickly and excellent rendering. It is a great choice for developing attractive and dynamic user interfaces.

Why use JavaScript vs React?

Unlike pure JavaScript, applications in React are not created as one long stretch of a file but as small building blocks called Components which are fundamental to React apps. Your entire website is divided into these small components which when put together complete the UI of the website.

For applications or larger websites, React is the best option. If your website is small and you don’t want to over-engineer basic elements, simple JavaScript is the way to go.

Does React support gradual migration?

React was designed to make it easy to adapt gradually. If you prefer, our developers can make use of just a few of its features while leaving others out for another day. Over time, our ReactJS development team can include more React features to your codebase. We have successfully incrementally migrated from other JavaScript libraries/frameworks to React for some of our clients.

What's the alternative to React?

When React was initially released the only competitor was Angular. Now there are more than ten libraries or frameworks competing with React. These include Vue (the most popular alternative), Ember and Aurelia.

Which companies use React.JS?

React is incredibly popular and is used by online business, large and small. Well known examples include Facebook (obviously), Instagram, WhatsApp, AirBnb, Dropbox, Netflix, Paypal and Slack. They will all hire experienced React developers on a full time or part time basis to keep their applications maximised.

What are the pros and cons of React.JS?

The advantages of developing in React.JS include the following:

  • React applications are faster with Virtual DOM, the virtual representation of a UI that is kept in memory and synced with the real Document Object Model
  • Builds are quicker because developers can reuse a previously composed component which ultimately means a lower overall cost
  • As React is a library, there is no frame-work specific code concerns.

The disadvantages of building in React.JS include:

  • It is important to stay up to speed with React software as it is continuously improved
  • JSX (JavaScript Extension) is difficult to learn and so experienced ReactJS developers are beneficial
  • Your app has to be structured which again is a skill easily delivered by a professional React.JS development team.
