I’m not a big fan of Javascript. It’s too flexible (dynamic) and the scoping of variables/functions is still completely counter intuitive for me.
But today I gave TypeScript a try. I believe it’s something Microsoft made and you can use it in Visual Studio. It’s strongly typed, has compiler time syntax checking etc. And it generates Javascript.

I spent too long getting a simple thing working. In the end it turned out to be a mistake in variable scoping (sigh).
But I have something! You draw rectangles on the canvas with your mouse (gasp!).

See the example at : http://www.goerp.nl/js/apptest1/default.htm

or an update at update: http://www.goerp.nl/js/apptest2/default.htm
Now it’s a lot of squares floating around eating each other, dieing etc.
