So far we only had effects that write something to the external world, we are not yet reading anything from the external world into our app. This lesson shows how we can change the DOM Driver to return a "DOM Source" representing read effects, such as click events.

You may be an exceptionally talented developer, but you might be an even more exceptional teacher. I love watching your videos. The way you build abstractions from the ground up is brilliant.
Many thanks! :)
