+Direct use of `charAt`, `slice`, or indexing is simple and readable for a fixed number of names but becomes repetitive and less scalable. 
+Using an array with `map` is concise, scalable, and handles missing names well, making it best for variable-length inputs. 
+Template literals or concatenation with `||` are concise and handle missing names, but are still repetitive for many name parts. 
+For flexibility, the array + map approach is generally preferred.
