I remember one accident I had when I was a kid walking up the stairs, holding one of those glasses in my hand, stumbled and banged the glass loudly against the stone of the stairs. Everyone was looking at me but apart from the loud kloink noise nothing happened to the glass.

Or use one of those toolboxes to create your psychology experiments: jsPsych, lab.js, OSWeb/OpenSesame.

And to put it online: JATOS.

Hi everyone, cognitive psychologist and author of lab.js (https://lab.js.org) here -- happy to answer questions about my research, and any of these projects!

Maybe, but then one can only really use compiled languages ... or isn't it a similar effort with JavaScript/Node.js, Python or PHP?
