Well there's your problem, you're using an operator that shouldn't exist. Triple equals all the things and if you want to coerce types write it out explicitly.

While you are basically right, the problem is that there is an operator that should not exist. Though that is not the biggest problem of JavaScript.

== is acceptable for null checks. And basically nothing else.

It should probably be replaced with a more bespoke operator for that, like x isempty or something.

["a"] + ["b"] = "ab"

Goodnight, everyone.
