About

I was thinking of a way to generate HTML without using strings as embedding strings in Javascript is a pain if they are multi-lined. There isn't a nice triple quote like there exists in Python.

So I took my inspiration from Lisp HTML generators that use S-expressions to generate HTML. I thought, hell, S-expressions are just a bunch of nested lists, I could do the same thing in Javascript.

I was a bit skeptical about a new data format call tnetstring. It claims to be both human and machine readable. They claim that a parser is easier to built for a tnetstring and therefore is better. In fact, while the implementation of the parser may be easier, human readability suffers with negligible speed gains.

I assert that if human readability is harmed in favor of speed, then you would be much better off using a binary solution such as Protobufs.
