HTTypeAny class
A type is both top
and bottom
, only used on declaration for analysis.
There's no runtime value that has any
as its type.
In analysis, you can do everything with it:
1, use any operator on it.
2, call it as a function.
3, get a member out of it.
4, get a subscript value out of it.
Every type is assignable to type any (the meaning of top
),
and type any is assignable to every type (the meaning of bottom
).
With any
we lose any protection that is normally given to us by static type system.
Therefore, it should only be used as a last resort
when we can’t use more specific types or unknown
.
