Can we add curly braces for for and if expressions?

if(!(sttc in function() {}) && Component.hasOwnProperty(sttc))

I don't know if hasOwnProperty will impact component inheritance. A test case should be helpful.

Written like that, a child class doesn't forward the statics of its parent. hasOwnProperty means the the property is in the object, not its prototype.

I am not sure of the question, therefore I don't know if it answers - what do you mean by "impact component inheritance" ?

Consider

@Compoent class Parent extends Vue { static config = {} }
@Compoent class Child extends Parent {}

Child.config // expect an object {}

Written like that, a child class doesn't forward the statics of its parent.

I think you already understand me. And I even suspect whether we should support inheritance any way.

Indeed, Child.config would, in this implementation, retrieve undefined
Beside beeing the easiest to implement, I just checked on how typescript managed static' legacy, and it seems coherent with the usual behaviour.

Let's keep it simple. vue-class-component is for both Babel and TS users. Rolling out a babel compatible version might be challenging.

So, is it still a "change requested" or an acceptation?

!(sttc in function() {})

Is this necessary? Looks like only using hasOwnProperty is enough.

This will for instance avoid statics to override name or apply

Why shouldn't they be overridden? Is that stated in the spec?
I think we should follow the es spec as possible since the user would expect it.

rv[sttc] = Component[sttc];

Can we rename rv to Extended and also sttc to key? I cannot see what the current name means...

return rv;
