That's nitpicking. Javascript was the only language that could be used to manipulate DOM so it's normal to conflate the two.

Well to nitpick your nitpick. Internet Explorer did allow you to use vbscript to manipulate the DOM.

Also you can use XSLT to create a new DOM tree in a browser from an XML document.

EDIT: I forgot about JScript vs JavaScript vs ECMAScript.

However much of this isn't relevant today.
