It almost means the same. Node is using V8 (from Chrome). Not sure if Nashorn has any asm.js optimizations but it will probably get it later if it is important to many organizations. Those are probably the most commonly used js engines out there.

Isn't node many, many versions of V8 behind Chrome? As far as I recall, they're on an out-of-date, unsupported version of V8 and sometimes cherry-pick patches from upstream, but that's about it.
