It is not Javascript code! Intead, you will find Python code in a script of type "text/python"
Brython is designed to replace Javascript as the scripting language for the Web. As such, it is a Python 3 implementation (you can take it for a test drive through a web console), adapted to the HTML5 environment, that is to say with an interface to the DOM objects and events
The gallery highlights a few of the possibilities, from creating simple document elements to drag and drop and 3D navigation
