1st way is to use props
<Row id = "someRandomID">
Wherein, in the Definition, you may just go
const Row = props => {
div id = {props.id}
}
The same could be done with class, replacing id with className in the above example.
You might as well use react-html-id, that is an npm package.
This is an npm package that allows you to use unique html IDs for components without any dependencies on other libraries.
