What Hacker News says

3 sources
It appears equality checks for objects is not supported i.e.: Immutable({a: 1}) !== Immutable({a: 1}) There is no built in equality function either [1] so that seems like that's a big advantage Immutable.js has over this. Maybe seamless-immutable-diff [2] could be a way to do it but I am not sure on the performance.
