In Python, you can just do "if len(array) == 0" or "if not array".

In JavaScript you have "if (array.length === 0)". Is there some problem
with that?

I would prefer this over your suggestion since it doesn't require some
variable named "empty" to have a sensible value set.

On the container test, as others pointed out, Python has the "in" operator.
JavaScript has a draft Array.prototype.includes method, but it doesn't have
broad cross-browser support yet.
