I need some guidance on a javascript quiz question. Please advise.

Here's the question: Set the 'greeting' variable, on line 29, by using the 'genericGreet' function in the context of 'andrew' with the array of arguments, 'args1'.

Here's the applicable code: var genericGreet = function(name, mood) { name = name || "you"; mood = mood || "good"; return "Hello " + name + ", my name is " + this.name + " and I am in a " + mood + " mood!"; }

  var andrew = {
    name: "Andrew"
  }

  var args1 = ["Michael", "awesome", ":)"];

Here's my answer: var greeting = genericGreet.call({name: 'andrew'}, args1);

Hi Mark,

You want to use the .apply method instead and then you can pass in the two arguments.

var greeting = genericGreet.apply(andrew, args1);

Hey Mark,

did you try using apply rather than call?

like

   var greeting = genericGreet.apply(andrew, args1);

I did but I think the way that I worded the context was giving me an error message. Meaning I don't think that I needed {name: andrew,.....}. I'm going to confirm. Thanks.
