What are the Characteristics of ReactJS?

Let's take a Look at Some of the Key Features of React


In React, we don’t use regular JavaScript to model, but JSX. JSX is a simple JavaScript that allows HTML references and uses this HTML markup syntax to render subcomponents. The HTML syntax is treated as a JavaScript call to the React framework. We can also write in simple old JavaScript.

React Native

React js has a native library, that provides an architecture for native apps such as iOS, Android, and UPD.

Unidirectional Data Flow

In React, a set of immutable values ​​is passed to the component renderer as an attribute in the HTML tag. The component can not modify any properties directly, but we can help us with the callback function.

Virtual Document Object Model

React JS is used to create a data-memory cache in memory that is used to calculate changes and refresh the browser. This allows a special feature that allows the programmer to code as if the entire page were rendered with each change, while the Repository only renders the components that have actually changed.

Why We Use React JS?

Now the main question is why you should use ReactJS. There are many open source platforms that facilitate the development of front-end Web applications, such as Angular. Let's quickly understand the benefits of React over other competing technologies or frameworks. As the front-end world changes every day, it's hard to spend time learning new structures-especially when the structure eventually becomes dead. So if you're looking for the next best thing, but if you feel a little lost in the jungle framework, we recommend considering React.


ReactJS is just easier to master. A component-based approach, defining a clear lifecycle and using simple JavaScript, makes React very easy to learn, builds a professional mobile and web app, and supports it. React uses a special syntax called JSX that allows you to mix HTML with JavaScript. This is not a strict requirement, developers can still write in pure JavaScript, but JSX is easier to use.

Easy to Learn

Anyone with a basic programming knowledge can easily understand this language, while Angular and Ember are called "domain-specific languages," meaning that it is difficult to learn. For the reaction, you only need basic knowledge of HTML and CSS.

Native Development

It can be used to create mobile apps. React is a big fan of reusability, which means support for a wide variety of code reuse. So at the same time we can make iOS, Android and web applications.

Data Binding

React uses unidirectional data binding, and the application architecture called Flux controls the flow of data to components through a control point (scheduler). It is easier to debug independent components of large ReactJS applications.


React does not provide any concept of dependent internal containers. You can use the Browserify, Require JS, and EcmaScript 6 modules, and we can automatically insert dependencies through Babel, ReactJS-di.


The ReactJS application is very easy to test. You can think of a React view as a state function, so we can use the state to operate and then pass it to the ReactJS view and see the actions, events, functions, and so on.
