It’s more subtle and monumental than that. Before this JS was already executing at the same speed as Java except for in arithmetic. At this rate of improvement eventually JS will execute much faster than Java in all areas except arithmetic where it will achieve near parity. I am not seeing any other programming language continuously improve their execution speed this much.
