Append to the end of this `Json` object's array the specified move‐insertable `json`/`array`/`object`/`number` and return a non‐`const` reference to this object. `json`/`array`/`object`/`number` is left in a valid but unspecified state. If `isNull`, then the type is changed to array. If an exception is thrown, `*this` is unaffected. Throw `bsl::length_error` if `size() == maxSize()`. The behavior is undefined unless `isArray()` or `isNull()`.
