eslintrc.shared

        // These are rules that are shared by all our javascript, no matter
// where it is written (in webapp javascript files, inside html
// <script> tags, in node.js scripts).
//
// In particular, there are NO ES6 OR ES7 rules here, since browsers
// do not support them yet.  Look in `eslintrc` for those rules instead.
//
// This rc file is not meant to be used directly; rather it is extended
// by the user-facing files eslintrc, eslintrc.browser, and eslintrc.node.
