    Short Answer: Ignore these warning and work on your project

    This shows that create-react-app or packages installed by this uses deprecated dependencies. This will not affect you development if you are just starting out react development. In any case you have following ways to proceed:

    1. Proceed Anyway

      You can continue using this as these won’t prevent you from working if you are just starting out or your project is not highly critical.

    2. Use any react app creator e.g. vite
      Although it doesn’t guarantees that you will not get these warning while using vite but you can try npm create vite@latest my-app -- --template react

    3. Update the deps manually (Might break react or related packages in you project)

      You can use npm-check-updates package to manually check for deps and update them.
      Install it using npm install -g npm-check-updates and then run ncu -u and npm install in your project folder. This will find and update to newer versions of dependencies but it might break the packages that specifically depend on older versions.

    So you best bet is to ignore these warnings and go on.

    While these warnings indicate that certain packages are no longer supported and may have issues, they don’t necessarily prevent you from creating a new React app.
    You can type y and then enter to continue. Despite of the warning it should still work.
    Alternative approach which I would like to suggest is

    npx create-react-app@latest my-app

    This make sure that you are using the latest version of create-react-app
