I am trying to build a demo app with Vue.js. What I am getting is an odd error that Vue is not defined.
<!doctype html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Vue JS Intro</title> </head> <body> <div id="demo"> <p>{{message}}</p> <input v-model="message"> </div> <script type="JavaScript" src="https://cdnjs.cloudflare.com/ajax/libs/vue/1.0.18/vue.min.js"></script> <script> var demo = new Vue({ el: '#demo', data: { message: 'Hello Vue.js!' } }) </script> </body> </html> What did I miss here? This is not a CDN issue as I also downloaded the library from the official website, used it and got the same result

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/1.0.18/vue.min.js"></script> and then:
<script> var demo = new Vue({ el: '#demo', data: { message: 'Hello Vue.js!' } }); </script> type="JavaScript" should be type="text/javascript" (or rather nothing at all)

Sometimes the problem may be if you import that like this:
const Vue = window.vue; this may overwrite the original Vue reference.
