  Discontinued ECMAScript proposal: String.prototype.replaceAll

  

The replaceAll() method also accepts regular expressions. So, if regex is your thing you can use it as well. You can also use a function as the replacement. If you do, this function will be executed for each match in the string. You can read this proposal in the official repository.

• proposal-weakrefs

  Discontinued WeakRefs

  

One important thing about WeakRef and finalizers. The proposal for this feature itself advises not to use them. One reason is that they can be unpredictable. Another one is that they don't really help garbage collection do its job. They can actually make it job harder. You can read more about the reasons in the proposal.
