There are many tutorials on how to get started with the Redux pattern in Angular 2, and how to use its essential concepts like store or effects. But often you'll find that those tutorials don't work for you -- maybe the author omitted something that was self-explanatory to them, or maybe (and that's a fact) Redux-related packages in npm change so often that the code in the tutorials from a few months ago does not compile anymore. So let's throw in another tutorial that will be obsolete just as soon, shall we?

Tooltips are a useful thing. Just last year, as a volunteer web developer, I built an event website for a nonprofit. The website had a page with the event program grid. The event had several parallel tracks, each of them jam-packed of back-to-back panels, and each panel had several panelists. Understandably, the web page real estate was at a premium, and the page for the panel grid listed the participants by only their last name. No other info.
