conditionally add prop to a jsx element

I have a react app and am trying to pass down a prop to a jsx element based on a condition. The element in question is an anchor tag and if the condition is true I would like to pass a rel="noreferrer" but if it is false I don’t want to pass down anything…

Like <a {...thisCondtion} or something of that nature.

Is there a specific way to do this?

Assume the condition either renders true or null (&& ternary) how would I pass down that prop correctly.
