Dart vs. Node.js vs. Go for Building a Web App

Which platform/language and/or framework(for the selected choice) should I use to build simple,fast, versatile, and feature rich web apps?(by feature rich I mean many useful packages to enhance user experience). I know JavaScript and some Java(taking AP course).

P.S: For Node.js, ES6, TypeScript, and other JS alternatives may be included. Just so no one starts hating on JavaScript's original syntax design flaws.
