A new technology (like, 12 months old new) landed in my Medium feed the other day. It was talking about a faster DOM renderer than ReactJS. Way faster.
I've only had a chance to read said document and some of the documentation for the technology stack. It does look interesting. Really interesting.
Here's a link to the documentation: http://imba.io/guides/essentials/introduction.
They use it here: https://scrimba.com/.
The original Medium document is here: https://medium.freecodecamp.org/the-virtual-dom-is-slow-meet-the-memoized-dom-bb19f546cc52.
Check it out!
