As we can see, unlike objects, keys are not converted to strings. Any type of key is possible. Although map [key] also works, e.g. we can set map [key] = 2, this is treating map as a plain JavaScript object, so it implies all corresponding limitations (only string/symbol keys and so on).
Can you use an object as a key in a map?

What’s the difference between a map and an object?
Map is a collection of keyed data items, just like an Object. But the main difference is that Map allows keys of any type. Methods and properties are: new Map () – creates the map. map.set (key, value) – stores the value by the key. map.get (key) – returns the value by the key, undefined if key doesn’t exist in map.
