Answer 1

i don't understand what's the problem, u expect the JSON to be at the second alert where there's undefined? which calls first ofc, because of the behavior of the async request, and it has nothing to do with react, it's a javascript thing.

if u need to run any code after there's a "questions" in the state, then u should use the componentDidUpdate and check if there's a "questions" in the state and then run the code.

if u would have used the React-Hooks it would be even easer :)
