CoffeeScript allows for embedding JS, but haven't tried jQuery in Framer Studio yet. http://coffeescript.org/#embedded
There are tricks and hacks, but the easy answer is no.
The main reason is that CoffeeScript is easier to get into (for item in list vs for (var i=0; i < etc..)) and it would be a mess if we had two languages. We might switch in the future if ES6 becomes a bit more mainstream / ready.
regarding jQuery: Include it in your project's index.html <head> and use $(layer._element) for targeting layers.
It's possible. But why!? 😁
Great feedback everybody. Thanks for your links and help.
Either way Framer is much faster for thinking through prototypes with code. It has certain constraints that are grounded and can still help you communicate to design and engineering the intent of your design.
Jason Vestri, I feel you man, I'm so used to jQuery's implementation of $.each, I even use it on Arrays and Object literals :PI do it like this:
And I put jquery.js in my modules folder
