Quick-tip: Web performance demos

A while back I wrote some performance demos for a presentation I was doing. The demos go into some depth for the following topics:

  • JavaScript download and thread blocking
  • JavaScript libraries and memory usage and execution times compared to pure DOM
  • Paints, invalidation and memory usage when creating layers

All of the demos include an in depth explanations on GitHub, so I won't bother rehashing this here. You can find the demos here: https://github.com/jornki/performance
