JavaScript

JavaScript - the language that graduates from "toy" to "hey, that's surprisingly nice" in 2005.

Ok, so throughout the site, I probably should be using "ECMAScript" instead of "JavaScript". For those detail oriented folks, just put on your mental word translators.

JavaScript also appears in...

in lots of browsers (often inelegantly)
in Flash - as their ActionScript scripting language
in Adobe products
in SVG (Scalable Vector Graphics)
