Closing Remarks & "One More Thing"

on YouTube ↗24m

" summary

Demo runs inside a web-based IDE that ships a full Hack type checker compiled to JavaScript so autocomplete, mouse-over type info, find-refs and jump-to-definition happen client-side in a web worker with no lag. Live breakpoints attach to HHVM so requests break, show call stacks and let developers inspect variables. Backend remains HHVM with request-isolated heaps; claimed performance is ~9x for Facebook workloads (about 2x for WordPress). Source release planned for late summer.
