As my first task at Pax Andromeda, I worked on (re)enabling all the JIT tiers for JavaScriptCore on Windows. This work has landed upstream in WebKit and JIT has been enabled by default on Windows. I’ll go into the background leading up to this, what changed that presented this opportunity, the work that landed, and some of the problems that came up along the way. If you’d like to join my team and work on WebKit, we’re hiring (remote US): reach out at ian@pax-andromeda.com.
