according to this page http://www.quackit.com/javascript/javascript_reserved_words.cfm javascript has some keywords which are from java, reserved. I also notice that with the highlighting in my editor. Is this to be future proof? Are they planning to implement some more OOP style operators into javascript?
I would love to se interfaces, abstract classes and things like that coming to js, but does the reservation of these words indicate anything?

Keywords are reserved words that are part of the syntax in the programming language. For example, const a = 'hello'; Here, const is a keyword that denotes that a is a constant.
From the ECMA-262 spec, §7.6.1.2 (Future Reserved Words):
And, from §2 (Conformance):
A conforming implementation of ECMAScript is permitted to support program and regular expression syntax not described in this specification. In particular, a conforming implementation of ECMAScript is permitted to support program syntax that makes use of the "future reserved words" listed in 7.6.1.2 of this specification.
