The video tutorial explains how to separate CSS from JavaScript bundles using Webpack. It introduces the Extract Text Webpack Plugin to achieve this, detailing the steps to configure Webpack for CSS extraction. The tutorial covers setting up source maps for both JavaScript and CSS, ensuring efficient development and production builds. It also includes testing the setup and committing changes to a repository.

Why is it problematic to have styles within the JavaScript bundle?

• It makes the JavaScript bundle larger and delays style application.

• It increases the number of HTTP requests.

• It causes syntax errors in the JavaScript code.

• It prevents the application from running in older browsers.

What is the primary purpose of the Extract Text Webpack Plugin?

• To minify JavaScript files.

• To compile TypeScript files.

• To extract CSS from JavaScript bundles.

• To optimize image loading.

Which command is used to add the Extract Text Webpack Plugin as a dependency?

• yarn add extract-text-webpack-plugin

• yarn install extract-text-webpack-plugin

• npm install extract-text-webpack-plugin

• npm add extract-text-webpack-plugin

What is the role of the 'plugins' array in the Webpack configuration?

• To include plugins that modify the build process.

• To configure loaders for different file types.

• To specify output file names.

How can you verify that styles are correctly extracted and linked?

• By checking the console for errors.

• By checking the file size of the JavaScript bundle.

• To improve the performance of the application.

Which source map type is recommended for development mode?

• hidden-source-map

• cheap-module-source-map

• eval-source-map

• inline-source-map

What change is necessary to enable source maps in CSS loaders?

• Add a new plugin to the Webpack config.

• Set 'sourceMap' option to true in loader options.

• Change the output directory for CSS files.

• Use a different CSS preprocessor.

Why is it important to commit changes to Git after modifying the build process?

• To reduce the size of the repository.

• To increase the build speed.

• To automatically deploy the application.

• To ensure changes are backed up and can be shared.

What command is used to push changes to a remote Git repository?

• git merge
