Use react scaffold to build the project

• Install globally: npm i -g create-react-app
• create-react-app hello-react
• Go to the project folder: cd hello-react
• Start the project: npm start

When executing npm start, an error occurred, please check the node version.

2. problem-solving

• The investigation found that it was caused by the node version.
• execute node -v ;

• react-app requires node version greater than 14
• execute nvm use 14;

• Just restart.
