JavaScript Code Challenge Help Needed

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

<!DOCTYPE html> <html lang="en"> <head> <title> JavaScript Foundations: Objects</title> <style> html { background: #FAFAFA; font-family: sans-serif; } </style> </head> <body> <h1>JavaScript Foundations</h1> <h2>Objects: Call and Apply</h2> <script> 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", ":)"];

  var greeting = genericGreet.call (args1);
</script>

</body> </html>

You are pretty close, but you are using the wrong method from the previous lesson. You are using the .call() method, but the quiz is looking for the .apply() method. I don't want to give you the full answer, but watching the video again, primarily starting around minute 9:00 should lead you right to it.
