Json.insert

// 1
template<typename  K, typename V>
requires std::convertible_to<K, Str> && std::convertible_to<V, Json>
bool insert(K&& key, V&& value) noexcept;

// 2
template<typename V>
requires std::convertible_to<V, Json>
bool insert(const std::size_t index, V&& value) noexcept;

1. If the internal data type is Obj, insert the specified key-value pair (overwriting if it already exists) and return true. If the type does not match, return false (no exception will be thrown).

2. If the internal data type is Arr and the index is within range (end index allowed), insert the specified element and return true. If the type does not match or the index is out of bounds, return false (no exception will be thrown).

Exceptions

None.

Complexity

1. Ordered map: logarithmic complexity; hash map: average constant complexity.

2. Linear complexity, depending on the number of trailing elements.
