That's a mistake I make often, but it's exactly because Javascript is different here from all other languages that I use.
Let's say I had to use a language with ':=' as assignment, I would still accidently type '=' all the time.

Well, so what? That's 250,000 out of maybe a hundred million bugs. I'm not saying it's good language design to have this behavior, quite the opposite. I'm saying it's not a big deal, especially considering all the other footguns in these languages. It's also not like these languages are going change it.
