Converts the output of a generator function to an array.

- Use the spread operator (`...`) to convert the output of the generator function to an array.

```js
const generatorToArray = gen => [...gen];
```

```js
const s = new Set([1, 2, 1, 3, 1, 4]);
generatorToArray(s.entries()); // [[ 1, 1 ], [ 2, 2 ], [ 3, 3 ], [ 4, 4 ]]
```
