Nice post! I recently started using fromEvent, cool stuff can be done with it also!
I started using it, for debounced input search, to not perform more requests than needed.
For observing inputs, you might consider using reactive forms and subscribing to the valueChanges observable on the form or formControl in question.
Ohh true, I did not consider this approach, I didn't like to have to pass in the element reference to fromEvent, I don't usually like manipulating elements directly so the reactive form could be a really nice solution.
Thanks for the info!
That won't help with enter key which is often used.
