A little Clojure-like LISP in JavaScript


Example from the web:
(alert "Hello world!")
Example from Linguist:
;; # wisp ; Wisp is homoiconic JS dialect with a clojure syntax, s-expressions and ; macros. Wisp code compiles to a human readable javascript, which is one ; of they key differences from clojurescript. ;; ## wisp data structures ;; 1. nil - is just like js undefined with a differenc that it's ;; not something can be defined. In fact it's just a shortcut for ;; void(0) in JS. nil ;; => void(0) ;; 2. Booleans - Wisp booleans true / false are JS booleans true ;; => true ;; 3. Numbers - Wisp numbers are JS numbers 1 ;; => 1 ;; 4. Strings - Wisp strings are JS Strings "Hello world" ;; Wisp strings can be multiline "Hello, My name is wisp!" ;; 5. Characters - Characters are sugar for JS single char strings \a ;; => "a" ;; 6. Keywords - Keywords are symbolic identifiers that evaluate to ;; themselves. :keyword ;; => "keyword" ;; Since in JS string constats fulfill this purpose of symbolic ;; identifiers, keywords compile to equivalent JS strings. (window.addEventListener :load handler false) ;; Keywords can be invoked as functions, that desugars to plain ;; associated value access in JS (:bar foo) ;; => foo["bar"] ;; 7. Vectors - Wisp vectors are JS arrays. [ 1 2 3 4 ] ;; Note: Commas are white space & can be used if desired [ 1, 2, 3, 4] ;; 8. Maps - Maps are hash maps, plain JS objects. Note that unlike ;; in clojure keys can not be of arbitary types. { "foo" bar :beep-bop "bop" 1 2 } ;; Commas are optional but can come handy for separating key value ;; pairs. { a 1, b 2 } ;; In a future JSONs syntax may be made compatible with map syntax. ;; 9. Lists - You can't have a lisp without lists! Wisp has lists too. ;; Wisp is homoiconic and it's code is made up of lists representing ;; expressions. The first item in the expression is a function, being ;; invoked with rest items as arguments. (foo bar baz) ; => foo(bar, baz); ;; # Conventions ;; Wisp puts a lot of effort in making naming conventions tra
