jsfiddle - Tutorial demo not working

Question

I'm reading the jsfiddle tutorial and copied the demo to jsfiddle: https://jsfiddle.net/cdt86915998/ps6shugt/. Running this demo in chrome and console gives Uncaught TypeError: undefined is not a function.

I suppose this error is caused by javascript configuration, but I already have jQuery(edge) configured.

This is my code:

$('test').addEvent('click', (function() {
    $('test').set('html', 'Goodbye World!')
    $('test').fade('out');
}));
