Set a cookie in JS on the script domain

I have a page on domainA.com

which calls a script <script src="https://domainB.com/script.js"></script>

can I set from script.js in javascript a cookie on domainB? Or I can only do it server-side with http header?

I tried with document.cookie = '..; domain=domainB.com;...'; but it nothing happens

JavaScript always executes in the context of the HTML document it is running inside.

can I set from script.js in javascript a cookie on domainB?

Not with client-side JS.

Or I can only do it server-side with http header?

Yes. This could be set in the HTTP response to the request for script.js.
