Which command generates a boilerplate version of a React application?

• A. npm init react-app
• B. npm install -g create-react-app
• C. npx create-react-app
• D. yarn create react-app

Answer: (D)

Bootstrapping a React project means quickly generating the standard project structure, scripts, and configuration so you can start building right away. Using Yarn’s create flow runs the create-react-app package to scaffold a new app, producing the boilerplate files and folders you expect (like src, public, a default package.json with start/build/test scripts, and a working React setup). It doesn’t require installing a global CLI; Yarn handles downloading and executing the create-react-app scaffolder and then creates the project folder you name. This approach is convenient and aligns with Yarn’s way of launching scaffolding tools. Other options either rely on a global installation, use nonstandard commands, or involve alternative tooling. The npx form is also a valid way to generate the boilerplate, but the given command exemplifies the Yarn create workflow. To use it, you’d run something like: yarn create react-app my-app.
