Do React developers use DOM?

I’m on my way to learn React but i don’t plan to use DOM, only to understand it. Do React developers use DOM?

Technically yes, but not as such. You just output React components, which ultimately output HTML, and React manages updating the DOM for you. In most cases in fact, you can’t update the DOM by hand like you would with jQuery or vanilla JS (there’s refs, but those are kind of a “back door” you wouldn’t use every day).
