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.
