Which directory contains the JavaScript that will be processed by webpack and is the heart of the React app?

• A. public
• B. node_modules
• C. src
• D. dist

Answer: (C)

The main thing being tested is where the actual code you write lives and gets ready for bundling. The JavaScript that defines your React components, hooks, and the app’s entry point is typically found in the source directory. This is the heart of the app because it contains the code that expresses how the UI behaves and how the app starts. Webpack reads from an entry point inside this directory, follows the dependencies, and bundles the JavaScript so it can run in the browser. The other folders serve different roles in the workflow. The dist directory is where the final bundled files are output after the build. The public directory holds static assets like index.html and other files that get served as-is. The node_modules folder contains the installed dependencies, not your own source code. So the directory that contains the JavaScript webpack processes and that forms the core of the app is the source directory.
