React Interview - (Part 3)

So welcome🙂 again to another part of React Interview series. So we’re finally now into part-3. Before I thought to bind up this series into total of 3 parts but there are so many questions to cover because React also includes JS. So hopefully this series will have total 5 parts.

So let’s cut out the introductory crap and jump directly into some more React interview questions.

1- What does useState return? 2- What’s the difference between React Router and React router DOM? 3- What are peer dependencies? 4- Can we use React without JSX? 5- Why do we have to use className prop and can’t have class as a prop to a component as a CSS selector?

_I'll be wrapping up this part of the article here. I'll be glad to read you answers to these question in the comment section._

_And don't forget to mention your approach towards taking interviews. How you approach it? And I know there might be some flaws🥺 in asking these questions so you are free to point them out._
