Type error unless there's an implementation of
+that specifies adding together and integer and a string.๐ฏ% accurate. funny how the typescript developer thinks this is some kind of "gotcha!"... like maybe just try a language besides typescript and find out for yourself ๐
"brought" ๐
my complaint is that typescript is stupid, yes. so why wouldn't i compare to what other languages do that is less stupid?
on the plus side, at least now i know that the ad-hominem minded devs came here too, and brought their righteousness with them.
OCaml ๐
Exactly. Most languages I know of that allow this at all will coerce the "1" to an integer and give x = 2. They get away with this because they define the "+" operator as taking numbers only as arguments, so if you hand them
x = x + "cheese"they'll error out.In the world of C and pointer arithmetic this makes perfect sense /s
I'm not sure if you're being rhetorical or not, but "string|number" is definitely correct here. A computer could definitely figure this out, but typing is for the benefit of the coders more than the code itself. It's basically functional documentation
Yeah that's what I'm saying, I hate it when coworkers will assign everything as "any" just to avoid the scary red squigglies. Oh well I guess that's what code reviews are for ๐
