They did the right thing highlighting a working example front and center.

Nothing worse than PDFs full of theory and no working examples of the thing you’ll actually be doing all day.

I get that it’s important to show what abstractions and methodologies can arise out of using it, but with a good example that would be obvious. It’s the developer community using the language that will come up with the best abstractions (libraries) that - if it has an active community - helps shape what those novel developer experiences are.

A good analogy is the development of the skateboard - released first as a scooter - until someone knocked the handle off a started “surfing” down the street. Just show me the thing. I’ll tell you if it’s cool and how to use it
