17,536 PointsThe challenge first asks you to listen for the 'error' event
request.on("error");
Then to pass a callback function (which here is simply a function passed as second argument to the 'on()' method)
request.on("error", function(){} );
This callback function will get called with an 'error' object as argument
request.on("error", function(error){} );
Finally, inside the callback you've just defined, you log to the screen the 'error.message' property, which is a string. To do so, they suggest you to use 'console.error()' instead of 'console.log()', but these 2 methods work very similar each other.
request.on("error", function(error){
console.error(error.message);
});
Hope this helps! :)

const https = require("https");
const request = https.get("https://teamtreehouse.com/chalkers.json", response => {
console.log(response.statusCode);
});
Second task: use the "on" method to retrieve the error, then print out with "console.error"
request.on('error', error => {
console.error(error.message);
});
