Enum members aren't subtype reduced in unions #35867
Description
enum E {
A,
B,
C,
}
function f(x: E | undefined) {
return x ?? E.C;
}Expected f to have type E, but instead it has type E | E.C
Doesn't have anything to do with ?? - can reproduce it with ||.
enum E {
A = 1,
B,
C,
}
function f(x: E | undefined) {
return x || E.C;
}
