It doesn't make it less valid, but "is JSX bad" has been done to death. It's been the subject of Medium posts like OP since I started using it in 2014. If you're "ramping up a team that's unfamiliar with JS and React," maybe you should be deciding whether to hire somebody experienced with JS and React instead of deciding whether or not to use JSX.

Agreed, the title was link bait done to death.

I'm not in the situation of ramping up a team unfamiliar as the author was. But it sounds like he was experienced with JS and React himself. Or are you suggesting he should replace his team with people more familiar with JS+React?
