JavaScript

JavaScript is a popular client-side web scripting language. It has higher-order functions and is by many accounts a jolly nice scripting language.

Implementation

There's a JavaScript implementation written in Common-Lisp in Mozilla at http://lxr.mozilla.org/mozilla/source/js2/semantics/.

Generating JavaScript Code

• Parenscript is Javascript with Lisp syntax and macros.
  
• jsgen is a similar package with a more direct mapping to JavaScript.
• parse-js is a simple ECMAScript 3 parser

Talking to JavaScript

JavaScript is also needed to implement the client-side part of AJAX (Asynchronous JavaScript And XML)-- a Common-Lisp implementation of which can be found as CL-AJAX for araneida and HT-AJAX for Hunchentoot.

If XML seems too heavy-weight one can use cl-json or st-json to directly send JSON (Java Script Object Notation).
