What build tool is used in the project? Have you worked with Webpack?

In most modern frontend projects, Webpack is used for bundling. It is a powerful modular bundler that allows combining various resources (JavaScript, CSS, images) into optimized bundles.

Yes, I have worked with Webpack, configured it to support ES6, Babel, CSS modules, and performance optimizations such as code splitting and tree shaking.

Here's an example of a basic Webpack configuration:

module.exports = {
  entry: './src/index.js',
  output: {
    filename: 'bundle.js',
    path: __dirname + '/dist'
  },
  module: {
    rules: [
      { test: /\.js$/, use: 'babel-loader' },
      { test: /\.css$/, use: ['style-loader', 'css-loader'] }
    ]
  }
};
