Others have already mentioned that you can replace "for (const k in props) elem[k] = props[k]" with "Object.assign(elem, props)"; further to that, in modern browsers, you can replace "for (const kid of kids) elem.appendChild(kid)" with just "elem.append(...kids)" - with the added benefit that plain strings passed to .append() get turned into text nodes automatically, so you probably wouldn't need $T any more:

Yeah, this evolved in my head from an early version that had to support IE, so it turns out there’s a bunch of cruft in it that I hadn’t realized wasn’t necessary any more. pcr910303 posted a version which uses the same APIs you mentioned, and I think I’m going to use that one in the future.
