Help for map on an array

Hello everybody,
I need help for map on an json array
15

It returns to me all the types but i can’t choose one with the key. Thanks!

I’m having trouble understanding your question, can you explain more what you mean by “It returns to me all the types but i can’t choose one with the key”?

Also, Is the example json array the value of datatTypes?
What should the end result look like, and what does it look like now?
