Javascript Foundations > Objects > Methods Code Challenge

I"m really pretty lost with what this code challenge is asking. 

On 'andrew' and 'ryan', set the 'greet' method as the 'genericGreet' function.

var genericGreet = function() {
        return "Hello, my name is " + this.name;
      }

      var andrew = {
        name: "Andrew"
      }

      var ryan = {
        name: "Ryan"
      }

The stuff I put in just came back "Bummer! Null".

Just take out the parenthesis after the function call.

Nice. Thanks, this helped. Stupid commas!

Just like name, you should have greet. And just like the strings you should have the function. I hope that wasn't to cryptic for you.

What is wrong here.

 var genericGreet = function() {
    return "Hello, my name is " + this.name;
  }

  var andrew = {
    name: "Andrew";  
    greet: genericGreet();

  }

  var ryan = {
    name: "Ryan"
    greet: genericGreet();

G S,

In andrew and ryan, you want a reference to the genericGreet function. But when you put the parenthesis after the function name, genericGreet(), then you actually immediately execute the function instead of saving a reference to the function in the object. Removing the parens should solve the issue.

Thanks Chris, that worked. I think it was also because I didn't put a comma after 'name: "ryan"' and 'name:"Andrew"', and also I didn't need semi-colons. 

      var andrew = {
    name: "Andrew",
    greet: genericGreet
  }

  var ryan = {
    name: "Ryan",
    greet: genericGreet
  }
