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 ]]
|
|
```
