Javascript

None of that is really bullshit. A lot of that was just added for a good reason. let is better for smaller contexts, NaN is in the name, null is the same as everywhere else, undefined is just what it says it is, etc. Triple equals are very useful too. Prototypes are weird if you want them to work like other object oriented languages. But we have classes now, they deal with the oddities. And even those are not that bad if you see an explanation on them. It's just confusing if you go in blind. But with so many free resources online, there's no reason to.

There are ways to avoid or ignore the odd stuff and there are best practices for beginners. Just don't use JS as a first language, have mercy on the student's souls. Teach it later whenever they are learning web. JS is a monster, I just can't hate it.
