Writes a JSON object to a file.

- Use `fs.writeFileSync()`, template literals and `JSON.stringify()` to write a `json` object to a `.json` file.

```js
const fs = require('fs');

const JSONToFile = (obj, filename) =>
  fs.writeFileSync(`${filename}.json`, JSON.stringify(obj, null, 2));
```

```js
JSONToFile({ test: 'is passed' }, 'testJsonFile');
// writes the object to 'testJsonFile.json'
```
