Explanation

In Express.js, you can send responses using the send() method of the response object (res). The send() method is used to send the HTTP response to the client with a specified response body. The response body can be of any type, but it is typically a string or an object.

Use

res.send() method can be used to send various types of responses like JSON, HTML, text, and XML.

Important Points

• res.send() method sets the Content-Type header of the response based on the type of data provided in the response.
• res.status() method can be used to set the HTTP status of response if needed.
