How to parse THIS json reply in react native - json

Question

I'am a noob in react native and i'am writing my first app to read a response from an API. Till now i know how to make the call and get the response and parse the regular replies in an array in the state, but i'am not finding the right way to parse the json reply of this specific form. I tried saving it in an array but its not working.

Answer 1

Firstly, entire response is inside object bracket {}.
So, response.activities will give array of a activities.
Then use it like var x = response.activities
var first = x[0]
var second = x[1]
and so on .

Answer 2

It was my bad for checking the "activities" array in the state by "console.log(this.state.activities)" in the ".then" that is right after the setState function. i thought the code won't move to the second ".then" unless done with the first, so it was getting parsed in the way rock stated but printed in the console before that.
