[Vuejs]-Vue… $ is undefined

Sounds like a hastily written tutorial, adding the jQuery library before or after the Vue library will solve your problems; However, I’ve found the main Vue examples / tutorials good enough to completely learn Vue.

I’d also highly suggest learning the .vue template (Single File Components). As later on it becomes much more valuable to your architecture and speeds up development quite a bit.
