Assign to this object the value resulting from first clearing this `JsonArray` and then inserting (in order) each `Json` object in the range starting at the specified `first` element, and ending immediately before the specified `last` element. Return a non‐`const` reference to this array. If an exception is thrown, `*this` is left in a valid but unspecified state. Throw `bsl::length_error` if `distance(first,last) > maxSize()`. The (template parameter) type `t_INPUT_ITERATOR` shall meet the requirements of an input iterator defined in the c++11 standard [24.2.3]providing access to values of a type convertible to `Json`, and `Json` must be `emplace‐constructible` form `*i`, where `i` is a dereferenceable iterator in the range `[first .. last)]`. The behavior is undefined unless `first` and `last` refer to a range of valid values where `first` is at a position at or before `last`.
