I have nothing to do with this but still I am getting second hand embarrassment. Here is an example, is-arrayish package, 73.8 MILLION downloads per week. The code? 3 lines to check if an object can be used like an array.
I am sorry, but this is not due to not having a good standard library, this is just bad programming. Just pure laziness. At this point just blacklist every package starting with is-.
