 ## Exception safety
 
-Basic exception safety: `value` is fully encoded -- including the checks below -- into storage owned by the document before anything already reachable from [`root()`](https://json.nlohmann.me/api/basic_json_document/root/index.md) is touched, so a failure while encoding `value` (an invalid argument, or `std::bad_alloc`) leaves the document completely unchanged, other than memory allocated for the encoding that is not reclaimed. A failure of a later allocation -- while `array` switches from its parsed layout to a growable block, or while that block grows, see [Notes](#notes) -- can still leave a partial effect, such as a null `array` argument already turned into an empty array even though `value` itself was not appended.

 ## Exceptions
 
-Throws [`type_error.308`](https://json.nlohmann.me/home/exceptions/#jsonexceptiontype_error308) if `array` is neither an array nor null -- the same message [`BasicJsonType::push_back`](https://json.nlohmann.me/api/basic_json/push_back/index.md) throws for the same type.

Throws [`type_error.316`](https://json.nlohmann.me/home/exceptions/#jsonexceptiontype_error316) if `value` is (or contains) a string that is not valid UTF-8, with the same message [`BasicJsonType::dump()`](https://json.nlohmann.me/api/basic_json/dump/index.md) gives for that string.

 ## Complexity
 
-Amortized constant, plus time linear in the size of `value` to encode it into the document's storage (constant for a scalar, linear in the number of nested values for an array or object): the elements of `array` move to a growable block of links the first time it is appended to (or [`set`](https://json.nlohmann.me/api/basic_json_document/set/index.md) on), and that block itself grows -- doubling its capacity, so the cost of growing it amortizes to constant per element -- only once it runs out of room. See [Notes](#notes).

 ## Notes
 
-Like [`set`](https://json.nlohmann.me/api/basic_json_document/set/index.md) on a member or an element, `push_back` never moves an existing element itself -- only where `array`'s *links* to its elements live -- so a view of an existing element of `array` stays valid across a `push_back`, but any iterator already taken over `array` is invalidated, since it was walking the old layout. See [Edits](https://json.nlohmann.me/api/basic_json_document/#edits) for what stays valid across an edit in general.
