1. In RESTful APIs, HTTP methods are used to perform different operations on resources. Here are
   the primary methods and their typical uses:

• GET is used to retrieve data from s server and is used when we want to fetch a list of users or
  getting details for a specific user.
• POST is used to send data to a server to create a new resource and is used when submitting
  forms or creating a new user
• PUT updates an existing resource and used to update the profile of the user
• PATCH updates an existing resource partially and is used to update the email address of the user
• DELETE removes a resource from the server and is used to delete the user account
• OPTIONS describe available communications options for a resource. Check which HTTP methods
  are supported for a resource (e.g, findin out if you can use GET, POST, etc, on a user resource).

2. 1xx (Informational):

Purpose: Request received, continuing process.
Example: 100 Continue - Request headers received, proceed with request body.

2xx (Success):

Purpose: Request successfully received, understood, and accepted.
Example: 200 OK - Request succeeded.

3xx (Redirection):

Purpose: Further action needed to complete the request.
Example: 301 Moved Permanently - Resource permanently moved to a new URL.

4xx (Client Error):

Purpose: Client-side error, bad request.
Example: 404 Not Found - Resource not found.

5xx (Server Error):

Purpose: Server-side error, failed to fulfill a valid request.
Example: 500 Internal Server Error - Server encountered an unexpected error.

3. Differences between the following responses.
   res.send():

Purpose: Send a response of any type (HTML, text, JSON, etc.).

res.json():

Purpose: Send a JSON response.
Use Case: Specifically for sending JSON data.
res.render():
