Thank you for the feedback and yes that's an area to improve on But the key property serves as a unique identity for each mapped item.

Is it safe to use the objects index in the array when no id property is available ?Akaeze Kosisochukwu

in my opinion no because the object index is prone to changing whenever we perform an operation on the object(like removing ,re-arranging)which makes it "not unique" with the rendered child. if no id is specified,you could use another property that remains constant regardless of changes made.
