When I started learning iOS dev, every tutorial pointed me at the interface builder. It drove me nuts because I'm doing this magic and things are happening but when something fails I have no clue what to do, and guess what: things failed a lot and for weird reasons when you used IB and didn't know how it worked under the hood. Granted JSX is far less bloated than IB, but its important to understand <Component /> bootstraps a react class component and <div> just renders a div.
