> One fun thing I did once is use the custom elements API to make a custom tag <element-template>. When the page sees <element-template tag=what-name></element-template>, it looks inside, finds any <template></template> <script></script> and <style></style> tags, and builds a new custom element with that tag name and all the powers. Cool but not incredibly simple.

I went a similar way: https://github.com/lelanthran/ZjsComponent

Not using it in anger in any prod system right now (finding the past, prior to AI, though), but all my side projects use it. Need to check and close any security issues this may have (not that I know of any yet. Should probably ask an LLM at some point about the danger of this).
