How to pass in an anonymous function?

Now, in the http.get() call pass in an anonymous function as a callback with the parameter response. This function is the second parameter in the get call.

I received this message. Bummer! missing ) after argument list

app.js 
var http = require ("http");
http.get("http://teamtreehouse.com/chalkers.json" function(response) );

Hi Jason! You're very close here. Because we're now passing in two things to the .get method we now need to separate those two things with a comma. Also, a function requires open and closed curly braces. Take a look:

var http = require('http');
http.get("http://teamtreehouse.com/chalkers.json", function(response){
});

Here we're sending in the URL and an anonymous function. Because these are arguments, they need to be separated by a comma. The response is sent in to the anonymous function, and that part you had correct. But we also still need the open and closed curly braces.

Hope this helps! :sparkles:

Thanks, Jennifer. I understand now. I just didn't see it the code challenge.

Is there a way to once an answer is marked best, to go back and review or saved it. In order to recall it, for a later code challenge, if needed?

Not that I'm aware of. I generally just keep a list of links in a text file with notes describing what the problem/answer was about :smiley:
