| // All these expressions are (bool)true: | |
| count([]) === 0; // Ok, that's expected. | |
| count(true) === 1; // Wait, I can count non-arrays? What does this even mean? | |
| count(false) === 1; // WTF? | |
| count(0) === 1; // yeah, obviously … | |
| count("") === 1; // I'm, starting to see a pattern. | |
| //Ok, so if I put in any non-array into count() it's going to be 1 because each is one expression, right? | |
| count(null) === 0; // http://ragefac.es/100 |
