 DOMPurify is written in JavaScript and works in all modern browsers (Safari, Opera (15+), Internet Explorer (10+), Edge, Firefox and Chrome - as well as almost anything else using Blink or WebKit). It doesn't break on MSIE6 or other legacy browsers. It either uses [a fall-back](#what-about-older-browsers-like-msie8) or simply does nothing.

We also cover Node.js v12.0.0 and v13.0.0, running DOMPurify on [jsdom](https://github.com/tmpvar/jsdom). Older Node.js versions are known to work as well.

-The resulting HTML can be written into a DOM element using `innerHTML` or the DOM using `document.write()`. That is fully up to you. But keep in mind, if you use the sanitized HTML with jQuery's very insecure `elm.html()` method, then the `SAFE_FOR_JQUERY` flag has to be set to make sure it's safe! Other than that, all is fine.
