Description mentions “7 juicy errors” but if you run tsc command, you get 9 errors? This course compared to JS Introduction is very poorly made.

I believe the compiler has been updated and the course has not.

there is also some dead code in here, and just generally sloppy code, that made identifying the type errors more challenging. but maybe that was the point?

  1. The numberOfClues argument in the doSleuthing function: It was declared but never used in the function.
  2. The let answer = 3; line: The variable answer was initially set to 3 but then immediately overwritten, making the initial assignment unnecessary.
  3. The return statement return "I couldn't figure out who drank the priceless milk. :( :(" in the doSleuthing function: This would never be reached due to the logic of the preceding code.
