If I set a custom header using php on the server side like this:
header('customheader: yay');
How do I receive this on the client side using javascript?

You will need to send another request to retrieve the headers. It's often not an issue if the url is cached. In this case, I will recommend you to use fetch API for the task.
fetch('/whatever/url').then(response => console.log(response.headers.get('customheader')));

no IE support developer.mozilla.org/en/docs/Web/API/…
use $.ajax().done() event jqXHR parameter
jqXHR.done(function( data, textStatus, jqXHR ) {});
Then call getResponseHeader() on the jqXHR object to get a list of response headers

Is this for a basic http request or just ajax? Looking for a general solution that uses pure javascript.

jqXHR is a wrapper with added properties, never the less getResponseHeader() is standard xhr.spec.whatwg.org/#the-getresponseheader()-method
