Q & A

  • What architecture changes are associated with Turbo DFG
    • Open to different ideas: first will be removing the baseline, definitely a possibility of a 5th tier, first replacing baseline
  • Finishing unified builds: will there be a bot to verify non-unified will still operate?
    • No specific plans, but a worthy idea
  • Native dev: WKWebView for Media Applications?
    • Many apps that use WKWebView want to control how media playback works
    • About control of video in a web view
  • How do you decide what’s important to do next?
    • We look at a number of factors
    • It used to be a judgement call, now we’re codifying
    • We look at a number of signals
    • How much dev interest?
    • is there a harmful aspect?
    • WPT areas are similar:
      • Most tests failing in Safari, but not in FF or Chrome
    • Sometimes we use high-value websites
