Kyle spends a few minutes explains how CSP can be applied to DOM events. He also demonstrates how he uses CSP inside of the Asynquence library.
(mystical music)…- Remember our fromEvent friend from the reactive side?…Here's how we could setup an event that listens…for dom events, I mean a channel…that listens for dom events.…I setup a channel on line two.…I attach a click handler to it.…And you notice on line four, I call putAsync.…Why am I not calling put?…Well, 'cause I'm not inside of a generator right now.…I'm inside of a click handler,…which is a plain old normal function.…
That putAsync would return me a promise, if I wanted…to listen to be told that the put had completed,…but maybe I don't care whether it completes.…I'm just going to put the event object into the channel.…And then, there is a real legitimate go routine…that's waiting to hear for that message on line 12.…He's trying to take from that channel.…So he's just spinning in a wild true loop.…And each time you click that, or each time you…do that event, I'm going to take, I'm going to get notified…by that, by being to take from the channel,…and I'm going to print it out.…
So what event am I doing?…
