const readText = async (blob) => {
    return new Promise((resolve, reject) => {
        const reader = new FileReader();
        reader.onload = () => resolve(reader.result);
        reader.onerror = () => reject('Incorrect blob or file object.');
        reader.readAsText(blob, 'UTF-8');
    });
};


// Usage example:

const blob = ...  // Hint: File is Blob so we can convert read file as text.

const text = await readText(blob);
