one liner to log to console a random element from the meetup.com attendee list.

meetup.comSelectAttendee.js

// copy-paste into console
console.log(Array.prototype.slice.call(document.querySelectorAll("#rsvp-list h5 a"),0).sort(function () { return Math.random() -0.5; })[0].innerHTML);
//click on the link to the profile

A good alternative is to call:

console.log(Array.prototype.slice.call(document.querySelectorAll("#rsvp-list h5 a"),0).sort(function () { return Math.random() -0.5; })[0].href);

You can have multiple members with the same name, but the link is unique (or should be at least 👅 )

A much better alternative:

var element = Array.prototype.slice.call(document.querySelectorAll("#rsvp-list h5 a"),0).sort(function () { return Math.random() -0.5; })[0]; console.log(element.href + " : " + element.innerHTML);
