I want to store a weak reference to an object in Javascript. I'm trying to implement a cache, and to avoid memory leaks I don't want to hold any strong references. I would use WeakMap or WeakSet, but those do not allow me to retrieve objects after they are inserted, defeating the purpose of a cache.
Is there any way to implement a "normal" weak reference in Javascript? Is there a work around I could use in my cache to avoid leaking memory?
Edit: See the duplicate question.
I ended up just using normal references and periodically emptying the cache to deal with memory leaks. Not a great solution, but that's Javascript for you...
