&quot;Symbol and definition lookup is another great feature of WebStorm. While Emacs can find symbols and definitions in a single file via Tern, ...&quot;<p>Actually, tern has <i>tern-find-definition</i> 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 <i>tern-pop-find-definition</i> to return back. For methods of native js objects tern even opens browser with related MDN page.
But WebStorm way better in debugging, that&#x27;s true.
