    That's fun! On what occasion did you spot it?

    Do you think it makes any practical difference? :)

      It was quite funny - during interview candidate have told me about (-1)*0 = -0 Just after interview I want to check this funny "fact". Terminal was open so I try this in nodejs. Myth was busted and I share this news with second interviewer. My second thought was to check this in chrome console and myth defend itself. I didn't share this news with second interviewer, but I hope he will read this blogpost.

      I think the interviewee would not be happy to know that his chances of getting a job are affected by the other interviewer's reading of your blog xD

      JS was out of scope so we do not care about this topic. It was just cool story.
