+# nlohmann::basic_json::rend
+
+```
+reverse_iterator rend() noexcept;
+const_reverse_iterator rend() const noexcept;
+```
+
+Returns an iterator to the reverse-end; that is, one before the first element. This element acts as a placeholder, attempting to access it results in undefined behavior.
+
+## Return value
+
+reverse iterator to the element following the last element
+
+## Exception safety
+
+No-throw guarantee: this member function never throws exceptions.
+
+## Complexity
+
+Constant.
+
+## Examples
+
+Example
+
+The following code shows an example for `rend()`.
+
+```
+#include <iostream>
+#include <nlohmann/json.hpp>
+
+using json = nlohmann::json;
+
+int main()
+{
+    // create an array value
+    json array = {1, 2, 3, 4, 5};
+
+    // get an iterator to the reverse-end
+    json::reverse_iterator it = array.rend();
+
+    // increment the iterator to point to the first element
+    --it;
+
+    // serialize the element that the iterator points to
+    std::cout << *it << '\n';
+}
+```
+
+Output:
+
+```
