React.js is a JavaScript library developed by Meta for building dynamic user interfaces, particularly single-page applications. It features a component-based architecture, a virtual DOM for efficient updates, and JSX syntax for easier UI management. Startelelogic, a software development company, offers services for projects utilizing React.js.

1. REACT.JS: BUILDING DYNAMIC USER
INTERFACES

2. Introduction
React.js is a powerful JavaScript
library for building dynamic user
interfaces (UIs). Created and
maintained by Meta (formerly
Facebook), it has become a popular
choice for developing single-page
applications (SPAs) and interactive
web experiences.
UnderstandingReact.js

3. Component-Based: React uses a component-based architecture,
allowing developers to create reusable UI components.
VirtualDOM: React uses a virtual DOM for efficient updating of the actual
DOM, which results in better performance.
JSX: JSX is a syntax extension for JavaScript that allows you to write
HTML-like code within JavaScript, making it easier to create and manage
UI components.
Features of React.js

4. Benefits of Using React.js
ReusableComponents:React's component-based
architecture makes it easy to reuse UI components
across the application.
EfficientUpdates:React's virtual DOM ensures that
only the necessary components are updated when
data changes, leading to better performance.
DeclarativeSyntax:React's declarative syntax makes
it easier to understand and maintain the code.

5. Getting Started with React.js
Installation:Use npm to install React and create-
react-app to set up a new React project.
CreatingComponents:Use the React.Component
class to create new components.
Rendering:Use the ReactDOM.render() method to
render components to the DOM.

6. React.js Lifecycle Methods
Mounting: Methods like constructor(),
componentDidMount(), and render() are called
when a component is first mounted to the
DOM.
Updating:Methods like
shouldComponentUpdate(),
componentDidUpdate(), and render() are
called when a component's state or props
change.
Unmounting: The componentWillUnmount()
method is called just before a component is
unmounted from the DOM.
