I have always considered React one of the frameworks that allows you to interop with regular HTML and JavaScript the easiest. The reason being that you can easily access DOM nodes and everything is run in JavaScript anyway. This is a lot more complicated in languages where you have a template language in my own experience.
That said, document.write is kind of special since it requires JavaScript to run while the HTML document is still open (so before it fires the loaded event). There is a reason this API is barely used today and mostly superset by appendChild.
