for the record: this is not a crash
from typescript.
@fatcerberus sorry, I didn't have the time to bisect the versions.
from typescript.
No, I just meant that you put
This is a crash
but itโs not - the compiler didnโt crash. Itโs just not doing what you expect
from typescript.
I suspect this is just a caveat of #29011, you're calling a union of overloaded and generic methods. Feels like a design limitation to me (just a nosy bystander and not a TS team member)
from typescript.
@jcalz Thanks for your insights.
The caveats are that only one type in the list of union members is allowed to have overloads, and only one type within the list of union members is allowed to have type parameters.
I didn't fully understand that post, but I think it's a little different:
As @weswigham described, and as I understand, it will at least get an intersected signature (suggestion) between A
and B
? which is "2"
in the above case. but in the similar case of HTMLDivElement
and HTMLSpanElement
, this seems doesn't work.
