Sorts an array of objects, ordered by properties and orders.

- Uses `Array.prototype.sort()`, `Array.prototype.reduce()` on the `props` array with a default value of `0`.
- Use array destructuring to swap the properties position depending on the order supplied.
- If no `orders` array is supplied, sort by `'asc'` by default.

```js
const orderBy = (arr, props, orders) =>
  [...arr].sort((a, b) =>
    props.reduce((acc, prop, i) => {
      if (acc === 0) {
        const [p1, p2] =
          orders && orders[i] === 'desc'
            ? [b[prop], a[prop]]
            : [a[prop], b[prop]];
        acc = p1 > p2 ? 1 : p1 < p2 ? -1 : 0;
      }
      return acc;
    }, 0)
  );
```

```js
const users = [
  { name: 'fred', age: 48 },
  { name: 'barney', age: 36 },
  { name: 'fred', age: 40 },
];
orderBy(users, ['name', 'age'], ['asc', 'desc']);
// [{name: 'barney', age: 36}, {name: 'fred', age: 48}, {name: 'fred', age: 40}]
orderBy(users, ['name', 'age']);
// [{name: 'barney', age: 36}, {name: 'fred', age: 40}, {name: 'fred', age: 48}]
```
