When the JSON pointer traverses intermediate levels that don't exist at all yet (not just a missing leaf), each missing level is created as an array or an object depending on whether the corresponding pointer token parses as a non-negative integer: a numeric token creates an array, a non-numeric token creates an object. For example, on an initially `null` value, `/foo/0/0/0` creates nested arrays, while `/foo/one/one/one` creates nested objects. This is not specified by the JSON Pointer RFC; it is this library's own, intentional disambiguation rule. See also [JSON Pointer](https://json.nlohmann.me/features/json_pointer/index.md).
Deprecation
Overload (4) also accepts a [`json_pointer`](https://json.nlohmann.me/api/json_pointer/index.md) whose template argument is a `basic_json` specialization (e.g., `nlohmann::json_pointer<nlohmann::json>`) instead of a string type. This is deprecated since version 3.11.0 and will be removed in a future major version; use `basic_json::json_pointer` (for `json`, `nlohmann::json_pointer<std::string>`) instead.
You should be warned by your compiler with a `-Wdeprecated-declarations` warning if you are using a deprecated function.
See the [migration guide](https://json.nlohmann.me/integration/migration_guide/#json-pointers) for how to update existing code.
