This .tern-project config works for me:

  {
    "libs": [
      "browser"
    ],
    "plugins": {
      "node": {},
      "es_modules": {}
    }
  }

Your project files must have "correct" format, e.g. require('relative_path') for imports and module.exports/exports for exports (or es6 import and export). Example for AMD format (requireJS) can be found here - http://ternjs.net/doc/manual.html#configuration

"Symbol and definition lookup is another great feature of WebStorm. While Emacs can find symbols and definitions in a single file via Tern, ..."

Actually, tern has tern-find-definition which works not only in a single file. You can jump in to other modules in your project or to node_modules. And there is tern-pop-find-definition to return back. For methods of native js objects tern even opens browser with related MDN page. But WebStorm way better in debugging, that's true.
