--description--

When a function or method doesn't take any arguments, you may forget to include the (empty) opening and closing parentheses when calling it. Often times the result of a function call is saved in a variable for other use in your code. This error can be detected by logging variable values (or their types) to the console and seeing that one is set to a function reference, instead of the expected value the function returns.

The variables in the following example are different:

function myFunction() {
  return "You rock!";
}
let varOne = myFunction; // set to equal a function
let varTwo = myFunction(); // set to equal the string "You rock!"

--instructions--

Fix the code so the variable result is set to the value returned from calling the function getNine.

--hints--

Your code should fix the variable result so it is set to the number that the function getNine returns.

assert(result == 9);

Your code should call the getNine function.

assert(code.match(/getNine\(\)/g).length == 2);

--seed-contents--

function getNine() {
  let x = 6;
  let y = 3;
  return x + y;
}

let result = getNine;
console.log(result);

--solutions--

function getNine() {
 let x = 6;
 let y = 3;
 return x + y;
}

let result = getNine();
console.log(result);
