Thanks! Can you add a unit test for this case in expand.ts?

I just checked and realized your new unit test fails. I'll leave it as an exercise for you to fix the test (hint: the expected output should have a $ in it).
The easiest way to test the repository is to open it in VS Code, open the integrated terminal, and run yarn; yarn compile; yarn test. You'll also want to install yarn on your device if you don't have it yet.
