The Visual Insight

Picture your data types as distinct islands in an archipelago. Your function is the explorer boat that sails between these islands and reads the name sign at each dock. It doesn't matter which island you land on; you'll always find the right name!

Crafting the Solution

1. Utilize JavaScript’s Native Typeof: Our first instinct might be to reach for JavaScript's built-in typeof operator. However, typeof lacks the specificity needed for custom and built-in objects like Array or Date. It often just returns 'object', which doesn't help us much.

2. Object’s ToString Method: In JavaScript, the Object prototype has a toString method that, when called directly, provides more specific information than typeof.
