JS has ECMAScript 1, 2, 3, 5, 6 points
Java has JDK 6, 7, 8, 9 points

Ask if you can ask why.

Java also has JAVA7 8 is only used to be 1.4 1.5

Js has ECMASCRIPT6

All have, the language must be with the progress of science and technology constantly updated to keep pace with the times!

If it is not updated, it is already obsolete.

No, no, you don't know.
