When I tried to start npm on the terminal, I got a message like this:

`Compiled successfully!

You can now view movie-app-2021 in the browser.

  http://x86_64-apple-darwin13.4.0:3000

Note that the development build is not optimized.

To create a production build, use npm run build.`

And when I clicked that site(url), there was nothing to open. In his lecture, there were two url which are the local and wifi on his terminal, but I have only one which is even not open.. what's the problem?

Help me 😭😭
