jinja2 variables in javascript

Question

If I have written jinja2 variables in javascript, for example

var array = [{{count}}...

and it works, will it work even if I move the code to a separate js file? Is there anything else I need to know about this practice?

You can certainly create a Jinja2 template that contains Javascript with Jinja2 variables, render that into a JavaScript file, and serve it to your users. Jinja2 doesn't care what kind of file you are rendering.

An important consideration is that you are changing a static file to a dynamic file. A typical Javascript file is static but you are now making it dynamic which puts additional load on your servers.

A typical solution is to use static JavaScript but render JavaScript data into your HTML page that the JavaScript file can access.

I came across this looking for the same kind of solution, and it was pointed out to me somewhere else that the data attribute in HTML is a good solution here as well.
