Or you can also use the transient/volatile versions of data structures and functions, but I wouldn't know where to learn about these in depth. I've seen them being mentioned briefly in some official docs on clojure.org and seen them in implementations of basic functions, like `reduce` and whatnot, but I'm still not very confident using them... Also, I had no need for more performance than what I get with the immutable data structures.
