The Best of Both Worlds
While functional programming works incredibly well for some problems, some have modifying state as a fundamental element of the solution. Although it may be possible to create a functional solution to such problems, they are easier to think of in a more traditional manner. In this chapter weâll stray beyond the pure functional subset of Clojure we looked at previously and see how it helps us create concurrent solutions to such problems.
In day 1 weâll discuss atoms, the simplest of Clojureâs concurrency-aware mutable datatypes, and show how, in concert with persistent data structures, they allow us to separate identity from state. In day 2 weâll explore Clojureâs other mutable data structures: agents and software ...
