:mrdocs:

Change the size of this `JsonArray` to the specified `count`. If `count < size()`, the elements in the range `[count .. size())]` are erased, and this function does not throw. If `count > size()`, the (newly created) elements in the range `[size() .. count)]` are default‐constructed `Json` objects, and if an exception is thrown, `*this` is unaffected. Throw `bsl::length_error` if `count > maxSize()`.
