Any engineer that allows any of the code like this in their codebase has only themselves to blame.

#16"
['1', '7', '11'].map(parseInt);
For what you would expect the output to be:
[1, 7, 11]
However, things get a bit off here, and the actual result is:
[1,NaN,3]
At first, this may look up very weird, but it actually has an elegant explanation. "
The elegant explanation is that JavaScript was taken over by psychopaths like bajcmartinez.
JavaScript is fine for button onClick code. Outside of that it's garbage.
