Not a JavaScript dev here, but I work with it. Doesn't "==" do type coercion, though? Isn't that why "===" exists?

As far as I know the operators ">=" and "<=" are implemented as the negation of "<" and ">" respectively. Why: because when you are working with sticky ordered sets, like natural numbers, those operators work.

Thus "0<=0" -> "!(0>0)" -> "!(false)" -> "true"

Correct me if my thinking is wrong though.
