How many ES5 environments are still in use today?

There's also JerryScript, which given their target platform, there's *no*
way they're going to be able to reliably implement much of ES6. They target
platforms like microcontrollers with less than 100KB of RAM and only a few
hundred in flash memory. One of their automated test devices really pushes
against it with its 192KB memory and 1MB flash memory. [2] (Their Raspberry
Pi is like a supercomputer compared to the other two.)

Also, BTW, Rhino is at least *attempting* to implement some ES6+ features.
