According to accepted answer I created promise returned function, so you can chain it.

function emptyBucket(bucketName){
    let currentData;
    let params = {
        Bucket: bucketName,
        Prefix: 'folder/'
    };

    return S3.listObjects(params).promise().then(data => {
        if (data.Contents.length === 0) {
            throw new Error('List of objects empty.');
        }

        currentData = data;

        params = {Bucket: bucketName};
        params.Delete = {Objects:[]};

        currentData.Contents.forEach(content => {
            params.Delete.Objects.push({Key: content.Key});
        });

        return S3.deleteObjects(params).promise();
    }).then(() => {
        if (currentData.Contents.length === 1000) {
            emptyBucket(bucketName, callback);
        } else {
            return true;
        }
    });
}
