Web development has evolved over the years. Right now, React Js is the most popular framework among developers because of its high performance, simplicity and flexibility. Many billion-dollar companies like Dropbox, Instagram, Walmart, Pinterest, Skype etc use React Js.
Most developers will find it easy to learn React Js, install it and start with web development. The documentation process is elaborate but clear. As React Js is so easy to learn and implement, it is a popular choice for many web developers and IT companies.
Most importantly, developers can supervise it through events, triggered outputs and functions. As per Statista, over 42.62% of web developers use React Js plus 10,752,498 websites are driving web development through React. Thanks to high demand, we have thousands of React Js developers across the world, especially USA and India.
Salient Features of React Js
The important features of React Js are as below:
1) JSX
JSX or Javascript XML is a Javascript extension syntax used in React that facilitates writing HTML and Javascript together. JSX is not a valid JavaScript, browsers will not be able to comprehend and implement it. Hence, React Js developers need transpilers to translate it and ensure browser compatibility. Furthermore, JSX provides developers a shortcut to work with React.createElement() while elucidating how the UI should render components.
2) Components
Components are the building blocks for React Js. Think of components as lego blocks that one can use to create working robots, buildings, vehicles etc. In the same way, React Js development companies and developers use blocks, also known as components, to develop complex applications. Many such components form an entire UI.
Developers can work on these components individually and build a mega component also known as the final UI. These components come in handy when developers work on extensive projects because it helps them maintain the code.
3) One-way Data Binding
React J's design is such that it will only support one-directional data flow. If React JS developers want multi-directional data flow, they will have to add more features. The reason for the one-way data flow is that the components & the data inside are unchangeable. The one-way data binding feature enables better control and flexibility to help developers work efficiently. Developers can follow any of the two conditions below for data-binding.
- Components to view - Any changes in the component data will reflect in the view.
- View to component - Any changes in the view will reflect in the component data.
4) Virtual DOM
A virtual DOM is a virtual depiction of the original DOM. React JS uses virtual DOM to enhance speed and performance. With the virtual DOM concept, you can sync the original DOM’s memory with the virtual DOM through a library like ReactDOM. Once React creates a new virtual DOM tree, it compares it with the original DOM using a diffing algorithm to determine the essential changes. After the comparison, it updates the necessary things only.
5) Debugging
Dev’s React community has a wide network of software developers (over 800k). Hence, testing is quite convenient with React JS. React JS developers can quickly navigate and find errors in the code while boosting productivity. They can use numerous tools and techniques to accomplish their debugging goals.
6) MVC Architecture
React’s MVC (Model view controller) determines the aesthetics of the application. MVC splits the architecture into three parts - model, view and controller. The model refers to data-related logic where the view is responsible for the application’s UI logic. On the other hand, the controller is an interface bridging the Model and the View.
7) Extensions
React comes with a bundle of extensions to support application architecture. These applications play a prominent role in application development while supporting server-side rendering, Flux and Redux. The biggest advantage of these extensions is that they enable React Js service providers and developers to provide custom functionality and content beyond the primary application.
