Enforcing an object type comparison function in the default comparator for a BST

[zrwusa]

Describe the bug
Enforcing an object type comparison function in the default comparator for a BST may impact performance; it’s worth considering a design change.

The Date type within object data types is essentially comparable.

To Reproduce
if (typeof a === 'object' || typeof b === 'object') {
throw TypeError(
When comparing object types, a custom comparator must be defined in the constructor's options parameter.
);
}
