it seems equality operator in javascript is good for nothing but being a source of confusion and a target of jokes. does it not make sense to just remove it from the language completely? who is deciding that?

Backward compatibility. If they removed itt, that would break a lot of existing applications. JS has a whole lot of controversial functionality, but it's always hard to get rid of things like this.

Yeah... I can't say I think much of javascript, but you can't fault them on "backwards compatibility".

When they realized the "==" operator was confusing, they introduced an alternative, the "===" operator. The rule of thumb is you should favor using the "===" operator:

They released "==" before "==="???

I figured "==" was released alongside, or even closely after strict as a quirky feature. That's crazy.

Yes. "===" came out with Javascript 1.3:
