I apologize, I was pissed off about things that didn't even have to do with software or computers.

JS is used mostly for frontend where you have to deal with css, designs and high level of abstraction. I don't expect to find something like this. Frontend devs spend most of the time dealing with the dom, frameworks and sending/receinving data toward/from the backend. But fine, you can do it. In the end this is just an opinion of mine.

It is not human readable, it is short and works and probably efficient but not easily understandable at first sight by people that usually don't need to use bitwise operators: 99,99% of js users. Clever but very bad practice.I am very curious to know the thoughts of the 95 individuals who clicked on 'best practice'. You are clever but those 95 are not.
