I'm trying to extract a value with a specified key. below are the data example;
example = [{'a':0,'b':2,'c':4}]
"results I want : 2"
To get the value of b, you would need to use example[0]['b']. You need the [0] since you also have an array enclosing the object.

In my code one of the promise returning the result like this
[{"success":true,"fileName":"./tmp/test.txt"}]
and I want to convert it into Json. how to convert it?
output:-{"success":true,"fileName":"./tmp/test.txt"}
You receive an array containing one object.
Just access array's first element, like :
var array = [{"success":true,"fileName":"./tmp/test.txt"}];
var fileName = array[0].fileName;
