list features in docs, that jumped over ES5.1 (ES6)

[arukiidou]

Class has been implemented at 0b5d210. It is great feature,
thank you.

At this time, static/private was also implemented. this goes beyond ES6.
People who come later, may missed this feature(even it's a great feature.).

Do you plan to list features that jumped over ES5.1 (ES6) in the Readme? or is it ok to contribute to the Readme?

I think it would be better to have a separate document and add a link to it from the README. The document should be a table with all ES6 features (i.e. features introduced in ES6, including not yet implemented) and ES6+ features implemented so far. The columns should be: Feature, Implemented? (Yes/No), Link to an issue (optional).

If someone could come up with such a table, it would be great.
