I am not very familiar with async/await and promises. Currently having two individual functions - to export files from X and upload those files to Y correspondingly.

export const exportFiles = async (A: string, B: string) : Promise<void> => {
    // statements to do the export
    return;
};


export const uploadFiles = async (C: string, D: string) : Promise<void> => {
    // statements to do the upload
    return;
};

When I try to make the function calls like:

exportFiles(A, B)
uploadFiles(C, D)

uploadFiles gets executed first since exportFiles is a time consuming function.

How do I program the order of execution? I want uploadFiles to start execution only after exportFiles gets executed fully.
