Basic Clojure

To try out LambdaCD, here’s what you need to know:

• How to install Leiningen (this is the build-tool we are using, like Maven in Java)
• Syntax
• (foo "bar" 5): this executes the function foo with the arguments "bar" (which is a string) and 5 (an integer)
• { :foo "bar" }: this is a map with a key :foo mapping to a value "bar"
• (defn add [a b] (+ a b)): this defines a function add with two parameters a and b that returns the sum of a and b

• You’ll also need an editor. LightTable is very popular at the moment, but you can really use anything. If you are used to IntelliJ, try out the Cursive
