About half the core JavaScript views have this notation I've never seen before, where HTML markup is right inline with the JavaScript, no delimiters. It gets handled like an object statement referencing a Mithril virtual node; and it transpiles into nested m() functions, so it seems like a Mithril thing, but I wasn't able to find anything about it in their documentation.
In fact, I wasn't able to find much at all, as it's difficult to make a search engine understand the difference between this and the very elementary reverse situation of JavaScript in HTML (about which there is no shortage of documentation).
An example of what I'm talking about
I am fairly new to web development, so I imagine I'm lacking a certain amount of context or vocabulary that would get me to a proper answer on my own. Whatever's going on, it's really cool. But what is going on with this?
