Introduction

LightScript is a scripting language for rapid application development for mobile phones.

• Documentation is available from lightscript.net in online and printable form.
• Latest source code can be downloaded from github.com/rasmusjensen/lightscript
• Updates on recent commits on twitter.com/lightscript

Features include:

• Runs on very low end mobile phone, requires only CLDC/1.0
• JavaScript/EcmaScript-like semantics and syntax
• Closures and first class functions
• Objects with prototypical inheritance
• Small size ( < 30KB code footprint) and fast execution
• Exceptions, object literals
• Good integration with Java
