json - How to convert json array to individuals entry

Question

I have json data like following way:

[2, 1, ["55", "54"]]

How can i get 55 and 54

Thanks

Answer 1

var arr = [2, 1, ["55", "54"]];

arr[2][0] // 55
arr[2][1] // 54

Answer 2

var a = [2, 1, ["55", "54"]];

This is an array. So, you access them by index.

here a[2]=["55", "54"]

To access 55

a[2][0]

To access 54

a[2][1]
