const filename = 'filename.test.js';
const extension = filename.split('.').pop();
Enter fullscreen mode Exit fullscreen mode

Or if you must have destructure:

const [extension] = /[^.]+$/.exec(filename) ?? [];
Enter fullscreen mode Exit fullscreen mode

But whichever solution that actually is able to select the very last part will work.
