Jerome Function Example

app.js

function add (a, b) {
  return a + b;
}

add;

What happens

function sayGordon() {
    console.log('Gordon');
}

function sayName(name){
    console.log(name);
}

sayName(sayGordon);

The output is the text ie code that makes up the function sayGordon(), that is why I said if a function is called without parenthesis the result it the text that makes up the function. You have said this is not correct, instead it is the value associated with the function.

Correct. If you console.log a variable that's a function, you'll get that functions text back!
