This is great. Everyone says react is easy and can be learnt in a day, and the docs/tutorials definitely make it feel that way. But then when you actually go to use it there are a bazillion funky patterns using new-ish es6 patterns and operators, and by the time you’ve implemented them they are outdated and no longer best practice because apparently there’s a better way now. So this list is useful.
People who think they have learned a framework in a day probably haven't learned too much.
