React.js development

A flawless user experience is the standard in modern web applications. The days of boring and static web pages are long gone. Our customers increasingly want custom features and want a web application that stands out from the competition to give their users a unique experience when using their product.

What is React.js?

React is an open source javascript library developed by the engineers at Facebook. It gives us, as developers, the ability to create lightning fast single page applications and paves the way to develop features that are tailored to your specific use cases. The library has rapidly gained popularity and is now the most used javascript framework in the world, with a market share of over 40%.

React uses the virtual DOM, or Document Object Model, to update web pages instantly. This means that React can render the DOM much faster than a normal page refresh can.

Why?

The DOM is actually a collection of nodes in a tree structure. Thanks to javascript you can easily add and remove nodes to create a more reactive application. Now, this is not necessarily slow. What is slow, is the browser re-rendering all your CSS for every DOM update. The Virtual DOM, on the other hand, is a light and decoupled abstraction of the real DOM. It is actually the user's browser that will keep a virtual representation of the UI in its memory. Whenever a status update is applied by javascript, the virtual UI in memory will detect it, compare it to the browser's current DOM and update only the sections that are different. This results in fewer changes to the UI and will inevitably speed up your application.
