why to store https.get () inside a request const in node js?

const https = require (https); const username = chalkers;

//* here is the problem const request = https.get(https://teamtreehouse.com/${username}.json, response => { console.log(response.statusCode); });

The ClientRequest object represents the request created by the "https.get" and is used to establish handlers to determine the status of the request and and to receive incoming data.

For more information, see the documentation page.

It sounds like you may be confused with how a "const" object can reflect any changes. But "const" doesn't mean the object itself cannot change, only that the variable cannot be changed to refer to a different object.

The callback in the "get" is often all that is needed, but you can use the stored request if required. For example, you could use it to create an error handler:

// this uses the "request" previously stored:
request.on("error", error => {
    console.error(error.message);
});
