Yes :)
This is roughly what I had in mind:
match obj with
{a, b : 5} -> return a + b
{a, c : {d, e : true}} -> return a + d
'rof' -> return 'lol'
Where the first clause matches if obj has the property a and the property b
that has the value 5.
The second clause works the same but recursively.
And the third simply checks if obj is equal to 'rof'.

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

*Subject:* Pattern matching?
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!
