Insert at the specified `index` in this JsonArray the specified move‐insertable `json`, and return an iterator referring to the newly inserted element. `json` is left in a valid but unspecified state. If an exception is thrown, `this` is unaffected. Throw `bsl::length_error` if `size() == maxSize()`. The (template parameter) type `t_INDEX` must be a non‐`bool` integral type. The behavior is undefined unless `index` is in the range `[0 .. size()]` (both endpoints included).
