> I’d recommend the immutable-js library for it. It has nice API and it comes from Facebook itself. Another option is the baobab library - but it works better when more ‘reactish’ ideas are present in your codebase, like global app state.

Another option is a library I wrote, react-cursor[1], which is basically sugar over the React immutability helpers[2] which the article mentioned. react-cursor has a couple advantages over immutable-js and baobab:

1/ simpler types: use regular react state with plain old js data structures, 2/ simpler implementation - about 100 lines of code and tiny api, 3/ super easy to integrate with your existing large codebase already using react state
