Could:

  • Move the assertion from inside the visitor to after the program.traverse call, to be 100% sure that it runs (I know you copied this pattern from the test above, but we can do better 🙂)
  • Replace .toBeFalsy() with .toBe(false) (since we expect false and not any falsy value)
  • Add an expect(program.toString()).toMatchInlineSnapshot() at the end, which helps when reading the tests to more easily see what's happening

Also, it would be good to have the following tests:

  • const a = 1, obj = { a };, renaming a
  • const { a } = 1; { const { b } = 2 } renaming a to b

I did another fix locally.
I don't think it's necessary to traverse twice to fix this, just add the ObjectProperty visitor.
At the same time I also found a strange thing, we also have an extra.shorthand in the AST, I don't understand why.🤔
