ReactJS is a popular open-source JavaScript framework for developing dynamic and responsive user interfaces. ReactJS, with its component-based design, stands as a particularly effective option for developing quick and scalable front-ends for mobile and web apps.
ReactJS is quickly gaining momentum among web developers as the leading JavaScript framework. The majority of development companies use React Development due to the various features it offers. Let’s take a look at the top 6 of them.
1. One-way Data Binding
ReactJS is designed to support one-way data binding or unidirectional data flow. This increases the application’s flexibility, which leads to increased efficiency. When a developer creates a React project, they frequently stack child components within parent components due to the unidirectional data flow.
That is, developers cannot directly change any component. A developer will have more control over the entire web application if they can see where and when an issue occurs.
2. JavaScript XML (JSX)
JSX is a syntax extension for JavaScript. ReactJS uses an XML or HTML-like syntax. This syntax is converted into React Framework JavaScript calls. It is a markup syntax somewhat similar to HTML that is used to define the look of an application’s user interface.
It nearly matches the syntax used by developers to construct React components to the HTML that will be injected into the web page. This makes developing the basic parts of ReactJS quick and simple for developers.
3. Virtual DOM
A virtual DOM object is a copy of the actual DOM object. It functions similarly to a one-way data binding. When the web application is modified, the complete user interface is re-rendered in virtual DOM form.
After that, the actual DOM will only update the elements that have truly changed. Then it compares the old and new DOM representations. This speeds up the application and eliminates memory loss.
4. React Native
React Native, like React DOM on the web, is a custom renderer for React. Native components are used as building blocks in React Native rather than web components like React.
A developer should be familiar with the fundamental ReactJS concepts in order to have a full grasp of React Native. Those are JSX, components, props, and state. React Native modifies React code to make it work on Android and iOS systems. Furthermore, it gives users access to these platforms’ inherent functionalities.
5. Components
Components are the building elements of any React application, and a single app is often made up of several components. A component is essentially a user interface element. For example, the ReactJS application is made up of several components, each with its own logic and controls.
These components are reusable, which aids in code maintenance while working on more significant size projects. In addition, ReactJS’s components play a significant role in shaping interactions and aesthetics in the apps.
6. Performance
ReactJS is well-known for its high performance. This characteristic sets it apart from other frameworks on the market today. This is due to the fact that it maintains a virtual DOM. The addition of virtual DOM offers benefits by comparing new data with the original DOM and immediately updating the view.
The DOM is fully memory-based. As a result, when we write virtual components, they are converted into DOM, resulting in smoother and quicker performance.
