async function uploadMultipleFiles(files) {

const promises = [];    //Creating an array to store promises
for (i = 0; i < files.length; i++) {
    const fileStream = fs.createReadStream(files[i].path)

    const uploadParams = {
        Bucket: bucketName,
        Body: fileStream,
        Key: files[i].filename
    }

    try {
        promises.push(s3.upload(uploadParams).promise())  //pushing each promise instead of 
                    //awaiting, to allow concurrent uploads.
    } catch (err) {
        console.log(`Error while uploading: ${err}`);
    }

    await Promise.all(promises).then(values => {
        console.log("values: ", values) //just checking values
        result = values;  //storing in a different variable
    });
    return result; //returning that variable
}
}
