Helps & Hints:
The main idea of a reduce function is that you are reducing the values in an array down to a single value.

When you use the javascript array method for reduce, many of the examples have a one line return for this method, but it can be easier
to return the result after performing your work.

```js
var sum = [0, 1, 2, 3].reduce(function(accumulator, current_value) {

accumulator = accumulator + current_value

return accumulator
}, 0)
// sum is 6
```
