Node.js and Jquery passing variables

I have a Node.JS Express application using Jade. I know how to send data from the backed to the front end using data.render({}). However, I cannot seem to give my jquery file js/script.js to get access to it. How can I pass in data to a front end js file?

Here is the answer

script(type='text/javascript')  
var frontEndData = !{JSON.stringify(backEndData)}
