TLDR; Ganslandt, Björn - Fighting Hardware Obsolescence With Greener Frontend Code

Björn delivers a very hands-on talk providing frontend engineers with concrete tips how to:

  • Select which browsers to support easily through probing
  • Supporting older browsers through JS/CSS overloading and fill-ins
  • Highlighting the importance to support older devices so that hardware can last longer. Just having a few devices saved on mobile pages can even be as relevant as reducing energy consumption for everyone bc of the disbalance of embodied emissions to operational emissions
  • Did you know you can detect if you have a modern JS browser with a simple one-liner like this: const isModernBrowser = typeof Array.fromAsync === “function”;
