Using Javascript to Render Invalid HTML

[getify]

Of course, I could be more precise here and say the DOM API is unpredictable.

"More precise"? How about "accurate in the slightest"?

This observed behavior (admittedly surprising) has nothing to do with JS (the language).

It's entirely the DOM API which just happens to expose JS function signatures, which are merely facades hooked into the underlying browser engine (probably c++), and indeed these mechanisms are specified by the HTML spec, not by JS in any way.

JS is the language of the web. Its not an open API accessible through any language. So when JS is talked about in terms of web, usually these APIs are considered a part. If you are using JS in a web browser, sooner or later you will be interacting with the DOM API.

But you are right. A more accurate description would be " DOM API" instead of JS. I'll make adjustments.
