What is the technology stack for rapid web application prototyping?

Question

JavaScript

Hello, I need to learn something for quickly writing web application prototypes. Applications are usually not the simplest, so installing some kind of php engine probably won't work. Familiar with Java and js.
Can you tell me which tools (languages, frameworks, etc.) I should pay attention to.

window.onscroll = (function(){

    ...
    ...
    ...
  }
})();
