[Vuejs]-My Vue CDN code is not working, my output says {{ name }}

New to Vue here too. Based on the script.js file it seems to me that you omitted the ‘mount’.

let two = new Vue({ el : "#test", data : { name : "Hello" } }).mount('#test')

Make sure that you include a string and (usually) a reference to an ‘id’ that exists within your HTML.
