Trouble with "Call and Apply" Challenge Question

I must be close, but something is off. I've put in

greeting.apply(andrew,args1);

but it's not working. What am I overlooking or missing?

Hi Annika,

You code is actually correct but the challenge wants you to write the code like this:

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

So does it want the .call method as opposed to the .apply method?

Thank you!

Do you have an easy & short explanation as to why it needs to be like that? I'll rewatch the video, but if you have time to explain it that would be great!

I appreciate the help on the challenge.

Both answers are correct. You did nothing wrong. I tested your code in my browser and it works fine. For some reason the challenge only accepts that 1 answer.

I believe the problem with your answer is that you would be calling the undefined greeting variable and trying to apply the Andrew object and arguments to it, and the challenge is asking you to set the genericGreet method with the Andrew object and arguments applied to it as the greeting variable.

Yes, I had the same problem, it's confusing what exactly is desired.

Thank you both (John Grillo & Annika Noren)

I had the same solution as Annika with the

|| greeting.apply(andrew,args1); ||

Watch the video like 4 times and was not putting the pieces together. John code of

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

Worked like a charm!

Avery Kachline, Glad to hear that || var greeting = genericGreet.apply(andrew,args1); ||

did the trick!
