There is a new method we are adding to the API that you can actually use to achieve this. Notice that is in preview, which means will be in production in a couple of months. You need latest Office version plus reference our preview office.js to try it. The office.js preview is here https://appsforoffice.microsoft.com/lib/beta/hosted/office.js

Check out this code sample on how easy is to do it.

 function onaddOpenDoc() {
        Word.run(function (context) {
          
          // this getDocumentAsBase64 assumes a valid base64-encoded docx file
            var myNewDoc = context.application.createDocument(getDocumentAsBase64());
            context.load(myNewDoc);

            return context.sync()
                .then(function () {
                    myNewDoc.open();
                    context.sync();
                }).catch(function (myError) {
                    //otherwise we handle the exception here!
                    showNotification("Error", myError.message);
                })

        }).catch(function (myError) { showNotification("Error", myError.message); });


    }

Opening a document in a new instance (i.e. a new, separate Word window) is, at least for the time being, not supported by the JavaScript-based Office.js API. You are always starting from a Context object, which will give you access to the currently active document via the Context.document property.

What you can do is insert content into an existing document, e.g. via the body.insertOoxml method.

Currently, the Office.js API is still limited as compared to the classic COM API. If you need the full feature-set you still might consider developing a COM or VSTO solution today. The only downside is that your add-in won't run on any platform other than Windows desktop.
