Hey y’all! It’s 2020 now and maybe some of you ask Why ReactJS Development is so popular and is it worth learning now? Let's face it - the digital world changes as we talk. Of course, it is difficult to adapt to trends in such a reality.
However, this is exactly what the big services and applications that everyone has heard in this direction are doing. Big apps like Facebook, Instagram, Netflix and others are constantly improving their experience and adapting to new frameworks and trends. Recently, there has been a lot of discussionі around ReactJS and its impressive capabilities. Honestly, ReactJS has its pros and cons, but over the years of its existence, it has gained incredible popularity. In this article you will read about numerous benefits of ReactJS, key features and advantages in the IT industry.
What is React?
Why do some of the largest companies use React?
●Facebook uses ReactJS, albeit in part. The mobile app is also built on a version of React called React Native, the essence is the same, although it is responsible for displaying iOS and Android native components instead of DOM elements. Interestingly, Facebook is where the ReactJS library was originally created, so it's obvious that they are using it.
●The role of ReactJS on Instagram is huge. Proof of this is numerous features such as geolocation, Google Maps API, search engine accuracy, and tags that fly out without hashtags. And all this is in the API of the application - which is really impressive.
●The React version works with Netflix as well - especially on their platform called Gibbon, which is used for low-end TV devices instead of the DOM used in web browsers. Netflix even posted an official blog post explaining how the ReactJS library can help to improve startup speed, performance, modularity, and other benefits. Netflix's UI engineers write this in a blog post: "A number of factors influenced our decision to adopt React, primarily: 1) launch speed, 2) performance, and 3) modularity."
●A couple of months ago, the New York Times came up with a great new project that mimics the look of the stars on the Oscars' red carpet. Obviously, this project's interface has been built into React and allows users to filter a gallery of different photos over 19 years. The re-rendering in this project is just one of the impressive features we can thank ReactJS for.
●Although, there were several beta versions prior to its official launch, WhatsApp uses ReactJS to build user interfaces too.
Key Features of ReactJS:
●React gives developers the ability to work with a virtual browser that is friendlier than the real one. The React virtual browser is a kind of intermediary between the developer and the real browser.
●React allows developers to declaratively describe their user interfaces and the state model (hereinafter - state) of these interfaces. This means that instead of describing each operation with interfaces, developers only need to describe these interfaces in terms of the final state (as a function). When some state changes occur, React will update the appropriate UIs based on the changes.
●In React, we describe user interfaces using components. You can think of components as simple functions (in any programming language). We call functions with some arguments, after which they return the result to us. We can reuse functions at our discretion and form larger functions from smaller functions.
●In the browser, we need to create HTML interfaces in the Document Object Model (DOM). With React, you don't have to worry about how to display these changes and even when to make those changes in the browser; React itself will react to changes in the state and automatically update the DOM at the right time.
In the end, development productivity with ReactJS, efficiency gains, and numerous organizational benefits are all the reasons why it is so popular and why large and famous applications are upgrading to ReactJS and taking advantage of the library's benefits. And despite every “framework” update that incurs some additional costs, none of this matters much when it comes to creating the perfect user interface - whether it is a web or a mobile application.
