No need to repeat what others said, but I'll also note that create-react-app is a website boilerplate generator and includes preconfiguration for tons of stuff including test frameworks etc. So yes, before you even open a text editor, you have eslint, jest, typescript etc all set up. Duh-doy, that's a lot of lines of code. Sigh…
