# --description--
ES6 introduced a shorthand object literal syntax:
```js
const a = 10;
const myObject = { a };
console.log(myObject); // { a: 10 }
```
First, move `sum` outside of `spreadsheetFunctions`. `sum` should be a function expression similar to `isEven`.
# --hints--
See description above for instructions.
```js
assert(sum([1, 2, 3]) === 6);
```
