> What can I even do from here as the newsletter author? Normally I like finding a teachable lesson. But it was 2 days of grueling debugging and somehow there aren’t any teachable lessons there.
A lesson to learn seems obvious to me: the V8 team did not communicate upfront sufficiently on the "oops our Math.abs() may return negative numbers, we fixed that in version X, be warned".
Which the V8 should be able to do in a "advisory for Google developers that work on high-performance client-side view rendering stuff" sort of weekly newsletter.
