Brilliant and actually humorous presentation. At first, I thought it was going to be some nerd deep-dive, but then it really was just a presentation of wats.
And honest to god, how do people program in JavaScript?

This is not to say that there's nothing else weird going on in Javascript, but the things people show off most as "wow, isn't this weird?!" aren't that consequential.
I know people just _want_ to bash JS because it's trendy, but come on.
That’s the problem. This is an unexpected situation and the JS philosophy is to silently do something that tries to make the best of it, rather than e.g. throw an error or warning.
I think it’s perfectly reasonable to bash JS for this. This is a direct consequence of the JS design philosophy. This is similar to the memory-safe vs memory-unsafe debate (except IMO, slightly dumber because I can’t personally think of any reason this is the behaviour you would want, whereas there might be performance reasons for memory-unsafe). It is increasing the bar of producing good code, without any actual benefit.
These issues pretty much all come down to implicit conversions, which you quickly learn to avoid as it’s usually unhelpful (likely a reason for typescript’s popularity).
