WEBApr 4, 2024 · Motivation. Clojure is written in terms of abstractions. There are abstractions for sequences, collections, callability, etc. In addition, Clojure supplies many implementations of these abstractions. The abstractions are specified by host interfaces, and the implementations by host classes.

WEBIt converts regular Clojure data structures right into html. For example, [:p "Hello, " [:i "doctor"] " Jones."] becomes <p>Hello, <i>doctor</i> Jones.</p> but it also does two extra handy bits of magic: it provides some CSS-like shortcuts for specifying id and class, and. it automatically unpacks seqs for you, for example:
