>Fascinating article. Maybe I'm old, but I remember when TraceMonkey was the wave of the future that was going to outperform everything, not a hairball they'll be glad to see the back of. I remember this too. It seems not so long ago I was reading benchmarks on shaver's blog demonstrating TraceMonkey's performance as largely comparable to the then-new V8. I agree that is kind of weird to hear that people hate the code and that Mozilla is throwing it out already. I have perhaps not kept super informed on Firefox's JS internals, just reading a stray article here and there, but it raises some concerning questions for me that something that was brand shiny new and a major development effort just a few years ago would be discarded as a "hairball" that no one wants to maintain anymore. I can understand how that can happen in a reasonable environment, but it can also be a sign of a seriously flawed process.
