Console.log data with template literals

When trying to log data sent from API URL, I intuitively use console.log(data: ${data}) in data event handler. And I expect I can get the same result as course did (each piece of data with buffer data type). However, I got the data with string type directly and there is only one piece of data. Following is the code and result I got. Can someone help explain what is going on? Many thanks!

Code

   const https = require('https');
   https.get(`https://teamtreehouse.com/${username}.json`, request => {
    request.on('data', (data) => {
        console.log(`data: ${data}`)
      });
   });

Result Result There is too much content for result so I just screenshot part of it.

You're still getting several pieces of data, but they are all being coerced into strings because of the template literal. Also, the abbreviation that the console.log function would have performed for you to make the display more concise is being circumvented for the same reason.

The original video code passed the data variable directly to the console.log function, which allowed it to identify the type and display it differently.
