Use mapObject to return a object from array passed as an argument which gets sqaured as math operation
|
Using an anonymous inner function scope we declare an undefined memory space using closures for storing a return value. We then use a new Array to store the array with a map of the function over it's data set and a comma operator to return a second step without needing to move from one context to another thank to closures and order of operations.

||||||
|
Notice the need to declare an order of operations(parenthesis) around the anonymous inner function so we can call it immediately.
