Immutability is baked into ClojureScript, so there’s no need for libraries like Immutable.js. Likewise, ClojureScript is all about manipulating a small set of code data structures (lists, vectors, maps, etc), and as such it has an extensive (!) set of functions built into the core language for doing just that, which eliminates the need for libraries like Ramada and Lodash.

Behind the scenes ClojureScript is transpiled to pure JavaScript with Google’s Closure compiler, so there’s no external dependencies on libraries like the ones mentioned above. It’s all just built into the language.
