I’m a JavaScript dev by trade. V8 was light years ahead when it came out, the specs on runtime compilation were off the charts. I’m not defending google by any means, but the work that went into V8 is how nodejs was created, and Firefox has adapted many of those learnings into its own JS engine. Google was and always has been a corporation for profit, but their engineers really pushed JS into a new stage with their engine, whether or not the browser around it was great
