5 reasons why we use React in RVA

Such famous platforms as Netflix, Facebook, and other popular resources are created on React. Today we will consider important features of the React library and discuss five reasons why we use it in RVA.


What is React? 


React is the most popular JS library these days. Even years after its release, its developers are still working on updates to make their product even better. 



The two main features that make React more than just a library are JSX and the virtual DOM. 


  • JSX combines HTML syntax with JavaScript, making it easier for developers to interact with the browser. 
  • The virtual DOM is a virtual copy of the DOM tree created by web browsers, which React creates to simplify the process of tracking real-time updates.


What is React used for?


The library is used for web development in React, and for building a website with React. In addition, the library also allows you to create React web applications. 


The main feature of React is components and states. Components are the part of the code that is responsible for the appearance of the platform. States are the components of a component that show all the necessary information. React JS has tools to manage these states. For example, Redux. This is a third-party state manager that scales better and more conveniently.


Another important feature of the library is support for React Hooks. These are special React features that allow a component's state to be extracted so that it can be tested and reused. With their help, developers can reuse state logic without changing the component hierarchy. React has both built-in hooks and the ability to create your own to be able to reuse code. 


But let's take a closer look at some other important features and benefits of the library to see why we use it in RVA.



1. React has a large community of developers


The library is one of the top five most popular repositories on GitHub, which means we are talking about an extremely large community. You can access a large community of experts to solve any problems. Whatever you're doing, there is a chance someone else has already done it and shared their experience on a personal blog or just posted code. Sometimes you can find several solutions at once and pick the best and most appropriate one for you.


2. Virtual DOM


Whenever there's a change in the HTML code, whether it's a user interaction or a value update, the DOM tree has to be redisplayed, which wastes a lot of time and energy. 


What is ReactJS in this problem? It comes to our rescue by using a virtual DOM. React simply creates a copy of the DOM, maintaining a cache of sorts. Every time we make a change, it looks through the virtual DOM and determines exactly which tree nodes and components need to be updated. Just a small change to the DOM allows the tree to be updated quickly and efficiently. This saves developers a lot of time and makes the application fast and responsive.


3. JSX improves the performance and efficiency of React 


Facebook developed it to extend the functionality of HTML into JavaScript. You can use declarative HTML syntax along with JS, which makes it very easy to manipulate static markup as if it were something very dynamic and flexible. 


Combined with the TypeScript library for data typing that we use in RVA, development goes to a whole other level. It allows us to solve problems before they arise. In addition, the typing makes it much easier for other developers to get acquainted with the project and work with other people's code.


4. No imposed architecture


React doesn't implement MVC or MVVM architecture, unlike other frameworks like Angular, Vue or Ember. Developers choose which architecture they prefer to build web applications with. React deals only with the UI layer, following a component-based structure, and leaves everything else up to the developer. This allows us to experiment or tweak the library for a specific project.


5. Flexibility 


React JS gives the developer complete flexibility. You can use it to create SPAs, hybrid applications, even TV applications. You can add as many external libraries and tools as you need and build a massive, complex web application. The library will ensure that the performance of your application is optimized.


Key observations


As mentioned in the article, the React framework is a very well-known JavaScript library used all over the world. It offers state-of-the-art functionality and is an ideal choice for developers looking for an easy-to-use, high-performance JavaScript framework. That's why we use it in RVA.
