          (+x) % 2 == 0
          

          If you forget for a second it’s Javascript, the language will turn back and bite you.

              This evaluates to NaN for some reason:

              '10' % 0
              

              Since JS doesn’t really differentiate strings from numbers, except on the places it does, it makes sense to make sure you are working with numbers.

                Oh right that. I guess I was visualizing a scenario where you already checked for it being a number, such as a Number.isInteger(x)

                also, that suprises me a lot, you’d think this is one of the places where it treats stuff as numbers

                the remainder operator should return a number or a NaN right? do we actually need the triple here?

                  Not really. But with JS it’s better safe than sorry.

                  The GP’s addition is unnecessary, but I fully support anyone that decides to do it.

              It makes sure x is a number.

                  And so wonderfully similar to the way that symbol is used in other languages as well. Gosh darn it I love JavaScript

        the is_even package does not provide much worth indeed because it simply negates is_odd and thereby all its benefit.

        It’s dependency is_odd on the other hand provides at least some additional checks (it also checks if the value is a valid integer below the max int value)

        And while I would indeed see uses for such methods (especially with the other checks, no simple oneliners) in some cases, especially in testing: This is stuff you write yourself, throw it in a e.g. NumberUtils class and everything is fine. You do never depend on an external library for that. The benefit (not spending a few seconds to write it) does not outweigh any of the drawbacks that come with external libraries.

        Make it faster and jankier with precalculated lookup tables!

            Screw calculating values for variables, just initialize it pointing to a random memory address and get a value for free! (Assuming your program doesn’t segfault).

      Vintage meme indeed.
