Internally, the container computes a hash table over the keys so that the complexity of lookups is in constant time, on average.
Internally, the container computes a hash table over the keys so that the complexity of lookups is in constant time, on average.在内部，该容器会对键值进行哈希处理，从而使得查找操作的复杂度平均保持在恒定时间内。

Similar to the `std` counterpart, elements may be accessed directly by their key with bounds checking using <<ref_object_at>>, or without bounds checking using <<ref_object_operator_lb_rb>> which creates a null element if the key does not already exist:

= `object` A <<ref_value>> stores an instance of <<ref_object>> as the underlying representation for a JSON object. Instances of the <<ref_object>> type are associative containers holding key and value pairs, where the key is a <<ref_string_view>> and the mapped type is a <<ref_value>>.
