  Hi,
  
  By the way isNaN is not the right way to check NaN in my opinion. Because isNaN("buggy") -> returns true also. We can check by Number.isNaN("fishy") or Object.is("fishy",NaN)

  @chety1:
  
  Hi chety1, you're technically correct. Though in the particular case of the video either isNaN or Number.isNaN works as it's following a parseFloat() instruction, which will return either a number or NaN, so no edge case here ;)
  
  But you're right as Number.isNaN() is often the one that should be used.
