create-react-app my-app --typescript vs. --template typscript

Question

What is the difference between

npx create-react-app my-app --typescript

and

npx create-react-app my-apptts --template typescript

?

The latter one is mentioned on the official documentation, but npm start for it leads to errors (that shall not be discussed here - at this question I just want to understand the differences between both commands)

I think --template typescript is the "new" way to create a typescript project. Before the v17 of react I was able to create a typescript project with --typescript flag but now It generates me js file instead of ts file. So now you jut have to use --template typescript — Hamza Khattabi

typescript flag has been deprecated since Create React App v4.0.0

We've removed the deprecated typescript flag when creating a new app. Use --template typescript instead. We've also dropped deprecated NODE_PATH flag as this has been replaced by setting the base path in jsconfig.json.

thanks for the official source. Using --typescript confusingly doesn't give an error.

Thank you. Yes indeed, they should've added some warnings to let us know that.
