Is this package still relevant?

[j-refs]

I see this was updated kind of recently. But your homepage is advertising es3 support? Which hasn't been the standard since the turn of the millennium?
So, my issue is:
It is very unclear if this package can/should be used in the modern es6 environment. What is the support for es6 on this?

Understand, it's very concerning to go library browsing and see a modern package tout support for such an ancient version, with no mention of modern support. Please update/explain support for modern JavaScript versions, so I may reconsider my choice to implement/support your project
