Does compiling to javascript preclude dart adding weak references?

I'm disappointed that dart doesn't feature weak references.

Is there something about compiling to a language which doesn't offer weak references which makes it impossible?

Dart wants to compile to performant JavaScript. That's why it needs to skip certain features (tail calls, for example). And I'd even argue that weak references are a bad idea anyway.

Yes.

In order to support weak references, you need a way to interact with or override the GC.
That is fundamentally impossible in Javascript.
