Insert into the `JsonArray` held by this object at the specified `index` the values in the range `[first, last)]`, and return an iterator referring to the first newly inserted element. If `isNull()`, then the type is changed to array and `index` must be `0`. If an exception is thrown, `*this` is unaffected. Throw `bsl::length_error` if `size() + distance(first, last) > maxSize()`. The (template parameter) type `t_INDEX` must be a non‐`bool` integral type. The behavior is undefined unless `isArray()` or `isNull()`, and unless `index` is in the range `[0 .. size()]`.
