Can you define DOM Helper?

I ran across the word DOM helper. I know what DOM stands for, but how 开发者_JAVA技巧would one really define the term DOM Helper?

A DOM Helper is basically a wrapper for the DOM and DOM Elements (html/xml, but usually html) that solves cross browser discrepancies and adds higher level methods making dealing with the DOM a nicer experience.

jQuery and DOMAssistant are both good examples of DOM Helpers.

A library that makes DOM manipulation easier by providing utility functions that do appending, inserting and such...?
