  I’m a JavaScript girl, I only know about null and undefined. But my guess would be N/A, just by method of elimination?

  ∞: They said the N-word, but if we ask “did they say the N-word yesterday?” and go back a day if the answer is no, we will be iterating forever.
  Overflow: They said the N-word sometime before Jan 1st 1970.
  NaN: Days since the last time they said the N-word: “yes”

    All these special values are from the spec for floating point numbers, integers don’t have them, in JS specifically all numbers are floats.

    An Option<int> does a good of showing intent.

    There are actually two interpretations of N/A:

    • N/A (not available): There is lost media so it can’t be evaluated.
    • N/A (not applicable): The show is in sign language so evaluating that is outside the scope of this string-matching program.

    Meanwhile, undefined seems to mean the value has not yet been evaluated. Maybe null is really the best.

    Sadly, JavaScript breaks the cadence :(

    Whaaat Javascript is famously known for being extremely weird with NaN values lol

      Yeah but we almost never use them intentionally. In almost any project, NaN only happens if there’s a bug. The others are regularly on purpose.

        People use NaN on purpose? 😨😨😨

  I mean, NaN implies there exists some value, it’s just not a numerical one. null days there is none at all.
