The main features David talks about in the post are available in vanilla JavaScript:
> If you're a JavaScript developer, I think taking a hard look at React is a really good idea. I think in the future, coupling React with a persistent data structure library like mori could bring JS applications all the way to the type of flexible yet highly-tuned architecture that Om delivers.
I think there are a couple reasons Mori and other libraries like it haven't caught on in the JS mainstream:
1. It's clunky to use them in vanilla JS compared to the default mutable objects and arrays. While you gain simpler semantics, the code becomes harder to read, and that tradeoff isn't always worth it.
2. Most JS developers are not experienced with building programs around immutable values.
