mapObject

 
Maps the values of an array to an object using a function, where the key-value pairs consist of the original value as the key and the mapped value.

 
Use an anonymous inner function scope to declare an undefined memory space, using closures to store a return value. Use a new Array to stor the array with a map of the function over its data set and a comma operator to return a second step, without needing to move from one context to another (due to closures and order of operations).
