We’d love to work with someone who can geek out on shadow DOMs, reactive programming, event driven interfaces, and similar topics. Prototypical inheritance and consuming several APIs doesn’t make you wince. Frameworks like AngularJS, React/Flux, and so on are familiar, but you can discern whether there may be a language, framework, or utility that would be the right fit for any given job. It also doesn’t hurt to have experience with C/C++, Java, Node.js, or Erlang.
