The video tutorial covers setting up a server to respond with data, emphasizing the importance of setting content types in headers. It demonstrates rendering HTML and handling different content types, including JSON. The tutorial also explains using custom headers and compares the HTTP module with Express, highlighting the ease of use with Express. The video concludes with a brief mention of HTTP status codes.

What is the purpose of setting a content type in the response header?

• To determine the speed of the response

• To indicate the type of data being sent

• To encrypt the response data

• To specify the size of the response

Why does a browser not render HTML when the content type is set to 'text/plain'?

• The server is not configured to send HTML

• The browser interprets it as plain text

• The HTML tags are incorrect

• The browser does not support HTML

What is a common use for non-standard headers in HTTP responses?

• To increase the response speed

• To provide information about the server technology

• To encrypt the response data

• To reduce the size of the response

What is the official content type for JSON data?

• application/xml

• application/json

• text/plain

• text/html

Why is it necessary to use JSON.stringify when sending JSON data in Node.js?

• To compress the data

• To convert the JavaScript object into a JSON string

• To increase the data size

• To encrypt the data

What advantage does Express provide when handling JSON responses?

• It automatically compresses the data

• It increases the server speed

• It simplifies the process by handling JSON conversion

• It encrypts the data by default

What is a typical structure for a JSON response object in an API?

• An array of numbers

• A string with HTML content

• An object with success and data properties

• A plain text message
