Call and Apply Challenge

Have trouble with this one. I know it's got to be simple, just can't see it.

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

 var andrew = {
        name: "Andrew"
      }

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

      var greeting = genericGreet;

Daniel;

Let's break this task down, it states:

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

The challenge gave us as a starting point:

var greeting = genericGreet;

Up on line 16 we can see the genericGreet function that has two arguments, name and mood.

The challenge is asking us to use the genericGreet function with 'andrew' and 'args1', so our code snipet would look like:

// Course: JavaScript Foundations
// Module: Objects
// Challenge: Call and Apply
// Task: 1 of 1

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

Does that help at all?

Thanks Ken, this was really helpful. I think I just wasn't clear on what the question was asking. For some reason, using .apply didn't register to me.
