Answer 3

I think so. PHP cannot something more than JavaScript. ASPX (programmed with C#) – the same case. Because JavaScript can everything that can browser. (Not everything, it cannot system context menu but ASPX and PHP either) But If you want really big website, I recommend TypeScript by Microsoft (You will need node.js).
