I am learning JS and very new to coding.
function querySelection(e){
console.log(document.querySelector(e));
}
querySelection('h5');
querySelection('#id');
querySelection('.className');
//querySelection('li: last child');
The very last query throws an error (commented). I am very new JS.I am not sure what is wrong in that query?

Change
querySelection('li: last child');
to
querySelection('li:last-child')

I have a site on domainA.com. It includes file.js from domainB.com:
<script type="text/javascript" src="http://www.domainB.com/file.js"></script>
In file.js, I want to be able to set a cookie for domainA.com. How would I do this? It must be possible since Google Analytics does it for their __utma, etc. cookies.

I'm an idiot--apparently, this isn't actually a cross domain cookie and you can set it using document.cookie='blah'.
