Yeah the playground is intended to show many directives to display the capabilities, but I wouldn't recommend making complex apps entirely with the iife version. It's mostly intended for templating (like conditional, iterations, htmx-like op).

The ESM version is better suited for small dynamic apps as you can handle context in a better way, and define helper functions rather than declaring them in a html attribute. It makes the code more readable too and this how you'd be able to achieve a more cohesive app.

As for the eval, it's true the doc advertise against, but maybe I was a bit too harsh about it. The reasoning behind avoiding it is the same as "eval()" in js. It's kind of a "god mode" (like you could do *eval="this.remove()") and it may mess up your final rendering as some internal reference may not be properly cleared if you do niche stuff. If you know what you're doing there's no particular issue with it
