My rule is that a functions' input and output should always be typed, even if it can be guessed. This to avoid mistakes when you refactor that function.
And to type anything that the compiler can't guess, like getElementById or JSON.parse. Often type it to unknown and write type guards. Anything else shouldn't be typed. You should never need to type already known types to unknown and back to a different type. You should never need to type to any except as a temporary fix for old code.

This was a great article, but I don't think typing a variable which the compiler can guess its a good idea...
Can you be specific about which lines this comment pertains to in the final repository?
