end() Function. The res. end() function is used to end the response process. This method actually comes from the Node core, specifically the response.
res. send() or res. json() should end all writing to the response stream and send the response. However, you absolutely can call next() if you want to do further processing after the response is sent, just make sure you don't write to the response stream after you call res.
You don't have to call res.end() if you call res.json(). res.json() calls res.end() for you.
