The basics of functional programming in JavaScript. No libraries required.

# Task

Given an Array of strings, use `Array#reduce` to create an object that contains the number of times each string occured in the array. Return the object directly (no need to console.log).

## Example

```js
var inputWords = ['Apple', 'Banana', 'Apple', 'Durian', 'Durian', 'Durian']

console.log(countWords(inputWords))

// =>
// {
//   Apple: 2,
//   Banana: 1,
//   Durian: 3
// }
```

## Arguments

* inputWords: An array of random Strings.

## Conditions

* Do not use any for/while loops or Array#forEach.
* Do not create any unnecessary functions e.g. helpers.
