Call and Apply challenges

Fellow coders,

I'm struggling with the following code challenge: "Set the 'greeting' variable, on line 29, by using the 'genericGreet' function in the context of 'andrew' with the array of arguments, 'args1'.

var genericGreet = function(name, mood) {
    name = name || "you";
    mood = mood || "good";
    console.log("Hello " + name + ", my name is " + this.name +
      " and I am in a " + mood + " mood!");
}

var andrew = {
    name: "Andrew"
}

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

var greeting = genericGreet;

Here is what i have tried

genericGreet.apply(andrew, args1);

greeting.apply(andrew, args1);

I'm baffled as i've tried it on my text editor and javascript and it works yet the code doesn't pass the code challenge.

Please assist. Thank you in advance.

The first of your tries should've worked. Have you assigned the return value to the greeting variable?

var someVar = someFunction.apply(someObject, arguments);

I just tested it and it works.

It worked. I don't know why it didn't work that I had planned for it to work initially though.

Thanks.

Thanks for responding Dino.

How do I assign the return value to the greeting variable?

Side note: what does the "Mod" next to your name represent?

The example I gave you is pretty much what you have to do, just substitute the names for the ones in the challenge, like this: var greeting = genericGreet.apply(...

The "Mod" next to my name means I'm one of the forum moderators here.
