The CSS Painting API allows you to create flexible, programmatic backgrounds that can dynamically adapt to element size and properties without using external images or heavy CSS animations.

A mechanism that allows JavaScript to manage multiple tasks efficiently in a single-threaded environment.

A file path tells the browser where to find a file (like an image, CSS file, or JavaScript script) relative to the current HTML document.

Check if the video is fully in view, and if so, play it; otherwise, pause. The muted attribute is added to ensure autoplay on most browsers.

Create a square element with the required dimensions, and throw in some randomness with the border-radius property to achieve a cool blob shape.

The <input> HTML element is used to create interactive controls for web-based forms to accept data from the user. A wide variety of input data types and control widgets are available, depending on the device and user agent. The <input> element is one of the most powerful and complex in all of HTML due to the sheer number of combinations of input types and attributes.

1. require vs. Import // ES5 var React = require('react'); // ES6 import React from 'react';

// ES5 module.exports = Component; // ES6 export default Component;

// ES5 var MyComponent = React.createClass({ render: function() { return( <h3>Hello JavaTpoint</h3> ); } }); // ES6 class MyComponent extends React.Component { render() { return( <h3>Hello Javatpoint</h3> ); } }

// ES5 var App = React.createClass({ propTypes: { name: React.PropTypes.string }, render: function() { return( <h3>Hello, {this.props.name}!</h3> ); } }); // ES6 class App extends React.Component { render() { return( <h3>Hello, {this.props.name}!</h3> ); } }

While JavaScript does not have a direct equivalent to structs, its objects can be used in similar ways to group related data and behavior.
