Explanation

Webpack bundles multiple JavaScript files like index.js and App.js into a single file so the browser can load them efficiently.

Code:

// index.js
import React from 'react';
import App from './App';

Explanation

Webpack allows importing CSS directly inside JavaScript files and combines them into the final ]build output.

Code:

import './styles.css';

Explanation

Webpack processes images and other assets so they can be used directly inside React components.

Code:

import logo from './logo.png';

Explanation

The entry property tells Webpack where the application starts bundling the dependency graph.

Code:

module.exports = {
  entry: './src/index.js'
};

Explanation

The output property defines the final bundled file that will be generated for browser usage.

Code:

module.exports = {
  output: {
    filename: 'bundle.js'
  }
};

Explanation

Loaders in Webpack transform files like modern JavaScript (ES6+) into browser-compatible code using tools such as Babel.

Code:

module: {
  rules: [
    { test: /\.js$/, use: 'babel-loader' }
  ]
}

Explanation

Plugins extend Webpack functionality, such as
optimizing bundles,
injecting HTML files
compressing assets.

Code:

plugins: []

Explanation

During production builds, Webpack optimizes files by
minifying code,
removing unused parts
improving performance.

Code:

npm run build
