including full DOM access？

[jinxiaoman]

including full DOM access？What does this mean? Can I write HTML? Get DOM node? alert? I didn't find an example, can you provide one?

It means you have access to the DOM similar to a browser environment.

You can get a DOM node via the DOM API methods such as getElementById(), you can also create elements via createElement().

You could write HTML by doing something like this:

document.body.innerHTML = `
  <div id="example">hello, world</div>
`;
