This looks interesting, it should be faster than generating (two) images for formulas (as preview and export). But how do I access the library correctly in QML? I tried:

import "katex.js" as Katex
...
property variant katex;
....
katex = new this.Katex();
...
html = katex.renderToString("c = \\pm\\sqrt{a^2 + b^2}", {
            throwOnError: false
        });

markdown-it.qml:73: TypeError: Type error markdown-it/katex.js:271: TypeError: Type error

Has "the internet" something to say about that?

Nothing of use to me. As a JS/QML novice, I'd expected the library to be called statically with katex.renderToString() or to be instantiated as a module like var katex = new Katex(). I don't get if this is a petty JS mistake or a missing step for QML.
