As far as I can read, Typed Objects/Structs are in consideration for a
later version of ecmascript (but not in the spec) and there exists some
implementations. It depends on the engine, but has there been any
thought to how costly they might be to fake at least some rudimentary
type support? For instance:
class point2D
{
constructor()
{
this.props=new Structure({
x:uint32,
y:unit32
});
}
setMe(x,y) {
this.props.x=x;
this.props.y=y;
}
}
This doubles the property lookups but that can probably be optimized
away (maybe) -- but it does force the engine to consider x/y as always
ints. Of course, this doesn't do anything about the function signatures.
I don't think types are coming anytime soon, and just wondering if, in
the future, messy code like this might be worth it, or otherwise, to let
implementers know this is something that people might try with their
code and would be an interesting path to look at.
