      That can be done better with a recursive function:

      function IsEven(number) {
      if (number === 1 return false;
      elseif (number === 2) return true;
      else return IsEven(number - 2);
      }

      Now it does all positive numbers :laugh: EDIT: because I get serious reactions on this code The code above is how NOT to do it - it's satire.

          I'm trying to guess what certain CPers would do if they were confronted with this person. JSOP - bullet in the guy's head to put both the guy and everyone else out of their misery. honey the codewitch - After she quit twitching, she'd write a parser to optimize the code. OriginalGriff - figures out how to turn it into a CCC clue Nagy - just wanders off, asking where the gin is. Me - I'd tell him to turn it all into a switch statement.

          I’ve given up trying to be calm. However, I am open to feeling slightly less agitated.

            You know... It's 2021, and the IRONY flows freely in all things... I expected to see a macro (written in JavaScript), that writes the javascript file: for (x..) if x % 1 == 0 write "if (number == " + x +") return false;" else write "if (number == " + x +") return true;" == And to see him asking people to crowd source running that file, to help him out! == Next question... Where is his test harness... Or is he caught in an infinite loop?

                        No...only positive integers. Since this is JS, some jerk could pass a float in and get your recursive function to march off the negative end of the numbers.

                            The AND denotes the decimal or fractional portion of the number. So Brits in the example above, Twelve whats?

                              And now this line of code is used: IsEven (4.2); It'll bounce around 0 until the heat death of the universe.

                                  Not in British English (or just "English", as it's known). :) "One hundred and twelve" === 112, not 100.12.

                                    function isOdd(x) { return isEven(x**-1**); } ? function isOdd(x) { return isEven(**~**x); } ?

                                    The sad thing is that that wouldn't work when testing against '1' as that would be testing to see if 0 was even and their isEven does not have a test for 0.

                                      The AND denotes the decimal or fractional portion of the number. So Brits in the example above, Twelve whats?

                                      The British English convention is to put an 'and' between any hundreds and non-zero tens/units and 'point' to indicate the fraction part. Therefore 123,456.789 is... "One hundred and twenty three thousand, four hundred and fifty six point seven, eight, nine"

                                        And 0. Is 0 even or odd? How can we know when that code is lacking the answer to this most important question?

                                        doesn't it throw an exception? :-\

                                          I'm trying to guess what certain CPers would do if they were confronted with this person. JSOP - bullet in the guy's head to put both the guy and everyone else out of their misery. honey the codewitch - After she quit twitching, she'd write a parser to optimize the code. OriginalGriff - figures out how to turn it into a CCC clue Nagy - just wanders off, asking where the gin is. Me - I'd tell him to turn it all into a switch statement.

                                          Me: Have Security dress the guy in a hazmat suit, and escort him out of the building. I'd then cordon off the area and decontaminate everything he touched on his visit - in an autoclave, by choice. This level of stupidity leaves traces wherever it goes.
