I intend to recommend adding a `.jshintrc` file to Django and ensuring JSHint conformance (django/django#2577).  I should note that recommendation in this DEP.

JSHint requires Node.js.  There may be feature-equivalent alternatives, but I am not aware of any that are actually used in the wild.

This is a valid point.  We could use a tool like [karma][] to run the tests in the browser.  I am not yet familiar with karma.

In every project I have worked on so far, all my JavaScript unit tests run in a single browser.  I have never had a problem with this, but I also use strict JSHint conformance so there are very few browser-specific bugs that could pop up in my code.

I may have a bias view of "industry standard" here.  I definitely think the functional/integration tests need to execute in multiple browsers, but I'm not so sure about the unit tests.
