MapKeys func returns all of the map keys as slice.

MapMap func iterates through the map and passes each value to the given mapFunc.

MapMapWithKeys func iterates through the map and passes each key and value to the given mapFunc.

MapReduce method reduces the map to a single value, passing the result of each iteration into the subsequent iteration:.

MapUnique method returns all of the unique items in the map as new slice.

SliceMap func iterates through the slice and passes each value to the given mapFunc.

SliceMapWithKeys func iterates through the slice and passes each key and value to the given mapFunc.

SliceReduce method reduces the slice to a single value, passing the result of each iteration into the subsequent iteration:.
