Some of these are (hopefully) common knowlwdge to react devs by now.

Although, even though I disagree with some things on that list. They're most certainly not considered good practices, but they're also not the end of the world, really. The "burns" they'd acquire when applying some of the these tips would lead to great learning opportunities too (without being major setbacks).

Overall, a very decent article for someone starting off with React!
