A lot of people mentioned other immutable JS libraries after reading my post. I thought it would be good to make a list of available ones.
There are two types of immutable libraries: simple helpers for copying JavaScript objects, and actual persistent data structure implementations. My post generally analyzed the tradeoffs between both kinds of libraries and everything applies to the below libraries in either category.
Libraries are sorted by github popularity.
- immutable.js - Facebook's implementation with a JS-like API
- mori - ClojureScript's persistent data structures exported to JS
Other libraries built on top of immutable.js: typed-immutable and immstruct
- React's immutability helpers
- baobab
- react-cursor (cursors)
- seamless-immutable
- cortex (cursors)
- tcomb (typed data)
- icepick
- mutatis
