# --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:
|
|
|
|
```js
|
|
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.
|
|
|
|
```js
|
|
assert(result == 9);
|
|
```
|
|
|
|
Your code should call the `getNine` function.
|
|
|
|
```js
|
|
assert(code.match(/getNine\(\)/g).length == 2);
|
|
```
|

let y = 3;

return x + y;
|

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