I like pattern matching but don't think it would work well for ES, although I'd
love to see a proposal that proves me wrong. My main concerns would be:
* What are you matching on? Constructor, `instanceof`, duck typing,
prototype etc
* What happens when one type can be coerced to another.
* What happens in the case that the matching identifier doesn't exist? -
such as with `Object.create(null, {})`

Are you thinking kind of like Rust's match statement? I think that something
like that would be quite a good addition.

Why is there no support for pattern matching in JavaScript?
I would guess that it has been proposed before, and if so why hasn't it been
included?
I have been thinking about it and I think it would integrate nicely into
JavaScript.
If it hasn't been proposed already I would propose it, and I would gladly look
into it more and try to examine what kind of semantics would be suitable.
Peace!
