I made a custom master page. I also made a custom CSS file, which I uploaded to "Style Library". I link to this CSS file by:

<SharePoint:CssRegistration name="<% $SPUrl:~SiteCollection/Style Library/coe/mainCOE.css%>" runat="server"/>

Now I want to make a custom JS file, and link to it in the custom master page. 1. Where should I upload the JS file, make a folder like the "Style Library"? 2. Is there a SharePoint way to link to the JS file, like the one above for a CSS file?
