could you please explain how to use the compiler if you did not install typescript globally? thanks

I tried "npx tsc" to compile to js but "export" keeps throwing a unexpected token error.

It's a bit hard to tell without having your project on hand, but did you happen to write your filename after npx tsc?

Here's what I found after some Googling :smile:

Since you are getting an "unexpected token" error related to the export keyword, it is likely because your environment doesn't support the version of JavaScript that includes export and import. Could you try adding the following line to the top of your TypeScript file?

export {};

This will create a module in your file, which will allow you to use export and import statements.

My mistake, I see now that it's written further up the error msg that I needed to add "type": "module" to package.json. Thanks for the help!
