Create the `calculate` function that will hold the code to sum up the user's calorie inputs. Leave the body blank for now. Here is an example of an empty function called `square`:
|
||
|
|
|
||
|
|
```js
|
||
|
|
function square() {}
|
||
|
|
```
|
||
|
|
|
||
|
|

See description above for instructions.
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(typeof calculate === 'function');
|
||
|
|
```
|
