Declarative HTML Binding in Only 20 Lines of Code! (and Signals)

Over the past few years I’ve said on many occasions that signals, a reactive primitive popularized by many JavaScript frameworks and libraries (and most easy to pick up using the implementation by the Preact folks), makes it much easier to add declarative binding to your HTML using basic vanilla DOM techniques + signal effects.

But I haven’t had a concrete example to show off just how simple yet powerful this can be… until now! 😎
