> or unit tests

Seriously! I write a documentation comment like:

    /// Given: blah
    /// When: blah
    /// Then: blah

and Copilot writes the test for me. I can generate a dozen tests like this and it's awesome. I write a lot more tests because of Copilot.

It even does an ok job with ‘rewrite this callback heavy code as async/await’ if you tell it which functions to use instead of ones accepting callbacks.
