> Fundamentally object-oriented, fundamentally garbage-collected And? No one said that the performance concerns reduce to hardware — but at the Java Applets days it was most definitely the primary reason for their slowness. Since then, with the improvements of JITs, it became very fast. > than a high-level object-oriented garbage-collected system can muster That’s not a well-defined performance level and the ceiling changes each year. And V8 has no real parallelism, so for many kind of workloads they are not drop-in replacements.
