JSSE: A JavaScript Engine Built by an Agent

dmitrygr: Now do it without those pre-written tests. Spec only. Else, the writers of those tests deserve a LOT of credit.

pseudosavant: It is pretty incredible to me that in the pre-LLM/agent coding world, creating a new high-quality JS engine or browser seemed like it would likely never happen again. But now, any large company could build one if they wanted to. In a single digit number of months no less.

Waterluvian: This is really cool to see and study. It’s a great experiment.I think it doesn’t really say a lot though. The hard part, in my opinion, is not making a new engine, it’s making one that’s worth using and will remain so for a long time.What I’d love to see next is how well (or poorly) this approach is at making the performance not terrible.
