--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;
let varTwo = myFunction();
Here varOne
is the function myFunction
, and varTwo
is 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--
--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);
