Depends what "whatever technology you're already most proficient with" is.
I think that any of Angular, Backbone, React, JQuery, Django, Rails, Node.js, PHP, and many others are fine for prototyping. Use whatever you're most familiar with.
However, if all you use is Java, or C++, or Google Closure - you're probably gonna have a bad time. Some technologies are built for mature projects with dozens to hundreds of developers. They pay a large tax to manage the complexities of large projects. If you're just starting out, you'll be paying that tax even though your codebase doesn't require it.
