Feature comparison between hyperHTML and lit-html. Compiled by hyperHTML author Andrea Giammarchi. lit-html is a similar project maintained by Google’s Polymer team. # 17th July 2018, 3:58 pm

hyperHTML (via) I’ve been playing around with multiline backtick template literals in JavaScript recently, and Claudio Cicali on Twitter pointed me to hyperHTML. It’s a fascinating project: it implements an alternative to React’s virtual DOM in just 4.6KB of code, taking advantage of the way tagged template literals can call a custom function which gets to affect how the interpolated values from the template are treated. The documentation does a great job of describing the various clever tricks that are used under the hood, in particular the way it takes advantage of the way tagged literals “freeze” the incoming array of literal chunks allowing hyperHTML to compile each template once and reuse the complied version for different interpolations. # 17th July 2018, 3:39 pm
