I say this to hope you feel better at work. I've been pressed into frontend web work and it's fractal complexity.
This might be the most hilariously ridiculous true statement I've ever heard.
x == x _ is true. Good.
x == !x _ is also true. Oops?
And guess what:
Array(3)==",," _ is also true.
But
NaN == NaN _ is false.
Math.max()>Math.min() _ is also false!
but then again
Math.max()<Math.min() _ is true.
Madness, I tell you!
I asked a friend that does web dev and it is apparently pretty idiomatic JS. Pretty appalling. I finally understood why people claimed it was "hard to get right".
x === x; // false
"With a combination of large ground-based FORTRAN programs and small spacecraft-based assembly language programs, [Real Programmers] are able to do incredible feats of navigation and improvisation -- hitting ten-kilometer wide windows at Saturn after six years in space, repairing or bypassing damaged sensor platforms, radios, and batteries. Allegedly, one Real Programmer managed to tuck a pattern-matching program into a few hundred bytes of unused memory in a Voyager spacecraft that searched for, located, and photographed a new moon of Jupiter.
The current plan for the Galileo spacecraft is to use a gravity assist trajectory past Mars on the way to Jupiter. This trajectory passes within 80+/-3 kilometers of the surface of Mars. Nobody is going to trust a PASCAL program (or a PASCAL programmer) for navigation to these tolerances."
You would be better off asking him about the veracity of the stories.
