Join Arthur Ulfeldt for an in-depth discussion in this video Sequence Manipulation, part of Learning Clojure.
- One of the features that really caught my attention…when I was first exposed to Clojure…was how nicely all of the functions in the core library…just seemed to work together.…You can take pretty much any function…and feed its output to the input…of pretty much any of the other functions…and you get reasonable, expected output.…This has a lot to do with one of these quotes…on the clojure.org/rationale page.…It says, "It really is better to have 100 functions…"operate on one data structure than to have…"a smaller number of functions…"that each work on their own data structures."…This way you get a sort of network effect…where the total value of your library…is the number of functions that can successfully…talk to the number of other functions times…the number of data structures they can work with.…
And I've found this has really held true…for the Clojure core library.…The main abstraction that makes this possible…is The Sequence Abstraction.…Most data structures have a way…to look at them from beginning to end.…
Arthur Ulfeldt covers the Leiningen build tool and setting up Clojure to work with the IntelliJ IDEA dev environment. He then reviews the basics of the syntax, including functions, expressions, values, macros, strings, and conditionals. He shows how to structure, compile, and deploy Clojure projects in Leiningen, and pull from Clojure's core library. In the final chapters, Arthur explores references and namespaces and points to resources to learn more about Clojure.
