React.js - robust and responsive interfaces that users love to interact with

If you think, you don’t know React, you are probably wrong. This open sourced JavaScript library  has powered Facebook’s and Instagram’s user interfaces since 2011, becoming  one of the   most popular solutions between digital companies that really care about a quality user experience and short time to market of their web and mobile user interfaces - including Airbnb, Netflix, Twitter, The New York Times, Pinterest and many more.

Why choose React.js for your frontend development

Development efficiency

Simply said: React.js is (probably) the  most efficient and flexible JS library to build users interfaces in  house. Instead of traditional big monolith HTML documents, interfaces are built of small and isolated blocks called “components”, and each of them can be replaced and moved with minimum effort. That greatly speeds up and facilitates development and testing, since the application can be rebuilt time after time and part by part instantly, without affecting other components.


Not only can the component configuration be easily rebuilt under React, its dynamic aspects are flexible as well. Let us take for example the shopping basket, a common element of marketplace apps. Once it is presented as an icon, on the other subpage - as a standalone product number, on the third - as an expanded product list with photos, amounts and prices. In the React-powered interface, it is still the same component, with dynamic parameters altered. React-based websites are very often designed as a Single Page App. That means the webpage is initially rendered from a single HTML file and all its further user interactions take place as state changes within the page, whilst server communication is performed via API.

Simplicity and consistency

While React components are the building blocks of the interface Redux is it’s memory and comm centre. As as “state container” this small and simple library stores and “broadcasts” all the changes in your application generated by the user. If  a product is added to the basket - information is stored in Redux. Someone  goes to the cash desk - React “listens” to the state change and gets the message about new products added. Apps written that way - called by Facebook team “Flux process” -  are much simpler and therefore more stable and debuggable than others, helping us save time and your money.

Versatility and low cost

Simple and consistent architecture of React+Redux combined with their simple API make them also extremely resource efficient in terms of code volume and performance speed. React.js owes a large amount of its speed to Virtual DOM. This is the in-memory cache representation of a Document Object Model - an HTML structure scheme through which JavaScript modifies  webpage content. React quickly calculates the website alterations based on Virtual DOM and updates the browser’s displayed webpage in the most efficient way. That means they work smoothly on older and budget hardware, also that means, they are easily implementable on different platforms like the web, Android and iOS environments as well, using React Native.
