Javascript ES6 is really a functional language now

I’m just clicking through and critiquing really. But I think it is a disservice to not be focussing quite heavily on functional aspects of the language, a typing and linting systems should probably be covered too.

Can I help?

FCC is an open source project and we would love your help.
There is an expanded curriculum currently in beta, which does include some more ES6 than the current curriculum does. You can contribute to the curriculum through pull requests to the GitHub repository. Or, if you prefer to write articles, you can contribute to the guide.
