title: Catch Missing Open and Closing Parenthesis After a Function Call
challengeType: 1
---
## 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.
## Tests
```yml
tests:
- text: Your code should fix the variable result so it is set to the number that the function getNine returns.
testString: 'assert(result == 9, "Your code should fix the variable result so it is set to the number that the function getNine returns.");'
- text: Your code should call the getNine function.
testString: 'assert(code.match(/getNine\(\)/g).length == 2, "Your code should call the getNine function.");'
```
## Challenge Seed
```js
function getNine() {
let x = 6;
let y = 3;
return x + y;
}
let result = getNine;
console.log(result);
```
## Solution
```js
