Features of React

05 2

React has several key features that contribute to its popularity in custom web development. Let’s cover some major ones:

  • Virtual Dom

React introduces a Virtual DOM, a lightweight copy of the actual DOM. The virtual DOM renders the complete user interface (UI) again whenever the application is updated or modified, updating the modified components. As a result, development takes less time and money.

  • One-way Data Binding

The term “one-way data binding” implies that the flow is one-way only. React only allows data to move in a single direction: from parent components to child components or top to bottom. The child component’s properties, or props, can communicate with its parent components to change their states in response to inputs, but they cannot return data to the parent component.

  • Declarative Syntax

React uses a declarative syntax that facilitates dedicated software development team in describing the intended functionality of a user interface component. Declarative coding makes code easier to comprehend and maintain and is more intuitive in React.

  • React Hooks

One very recent addition to React is React Hooks. Hooks are functions that let developers access state and lifecycle aspects in functional components. They were first introduced in React 16.8. Coders can write more understandable and concise code with the help of hooks like useState, useEffect, and useContext.

  • Hot Reloading

Like Blazor, React’s hot reload feature also allows dedicated React developers to instantly see code changes in the application without a full-page refresh. It preserves the application state, making the development process more efficient by quickly updating the UI during development without losing the current state or requiring manual intervention.

  • JSX(JavaScript Syntax Extension)

JSX is a syntax extension for JavaScript that enables mixing HTML-like tags with JavaScript code. React developers use JSX to describe the structure of UI components more concisely and readably. JSX is then transpiled to standard JavaScript by tools like Babel.
