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>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.
You can build the same quality of web app in any of the above. The question is how much you'll have to fight against the platform's pain points.<p>Will you be CPU bound? Will you be memory bound? IO bound?
Will you need to scale? it what way?
What libraries, frameworks, modules etc . . . will you need?
Will your app be isomorphic? Where will you host?<p>And if you don't have many answers just go with what you're most familiar with.
