Immerjs is close enough to language level immutable data structures that I don't miss them that much. I'm hoping the proposal for match syntax finally lands. Something like Swift's protocols would be nice. TS inherits some unfixable mistakes from JS but overall I find it a pretty comfortable and productive language.
