Plasma Programming with JavaScript

Plasma has built-in JavaScript (also known as ECMAScript, and often referred to as QtScript in the context of Qt) scripting support without requiring any external dependencies.

Plasmoids

Getting Started
Creating and running your first plasmoid in JavaScript
Getting Data
How to retreive data from a data engine
Now Playing
Slightly more advanced data engine usage: displaying what's currently playing
System Monitor
How to access systemmonitor data engine
Cheat Sheet
A cheat sheet, rather than a tutorial, of things to remember and watch out for when developing JavaScript plasmoids
API Reference

Other Applications Of Javascript

Scripting Plasma Shells
The KDE Plasma Desktop and Netbook provide means to manage the desktop shell (desktop, panels, widget) via scripts written in JavaScript. This article describes how to take advantage of this feature set as well as documents the full API. This is primarily a system administration tool, but may also be of interest to power users.
