Extract data from API

Question

Maybe the question might be too simple but I can't get the data

This is the response of API:

[{"city_id": 33, "city_name": "Nagpur", "country_id": 1, "country_name": "India", "entity_id": 33, "entity_type": "city", "latitude": 21.15, "longitude": 79.09, "title": "Nagpur"}]

this response is being stored inside "a", now when I set state,

this.setState({lat: a})

It shows the same data in the log but when I try to extract latitude and longitude it shows undefined. I'm doing this to extract data

this.setState({lat : a.latitude})  // shows undefined

Please Help me !!!!!!

Does this answer your question? [How do I return the response from an asynchronous call?](https://stackoverflow.com/questions/14220321/how-do-i-return-the-response-from-an-asynchronous-call) — AndrewL64, Feb 29 '20 at 23:07
Since it is an array, we can do get the value by index. Please refer @Ian Pilipski's comment — Kumar KS, Feb 29 '20 at 23:10

It looks like a is array in your response so try:

this.setState({lat : a[0].latitude})
