// The clear built-in function clears maps and slices.
// For maps, clear deletes all entries, resulting in an empty map.
// For slices, clear sets all elements up to the length of the slice
// to the zero value of the respective element type. If the argument
// type is a type parameter, the type parameter's type set must
// contain only map or slice types, and clear performs the operation

The [Map.Clear] method deletes all the entries, resulting in
