Creating a common file by combining two similar functions

I have two functions that are mostly similar in different files and I want to combine them into one file but as can be seen in the code, some product properties are different from each other and I want to handle this dynamically. What is the correct way to do this?

File-1:

function run(args) {
    try {
        var sitePreferences = require("sitePreferences");
        var pinterestHelpers = require("~/cartridge/scripts/helpers/pinterestHelpers");
        var maxRowLength = sitePreferences.get("pinterestProductFeedMaxRow");
        var hostName = require("dw/system/Site").current.httpsHostName;

        var products = pinterestHelpers.onBeforeStep(args);

        var fileNumber = 1;
        var lineCount = 1;
        pinterestHelpers.removeFiles(args);
        var csvObject = pinterestHelpers.createCsvFile(fileNumber, args);
        var csv = csvObject.csv;
        var fileCreationResponse;
        var fileWriter = csvObject.fileWriter;

        while (products.hasNext()) {
            var currentProductObject = products.next();
            var priceObject = pinterestHelpers.getPrice(currentProductObject);
            var product = {};

            if (pinterestHelpers.shouldBeExported(currentProductObject)) {
                if (maxRowLength !== lineCount) {
                    product.id = pinterestHelpers.getId(currentProductObject);
                    product.title = pinterestHelpers.getTitle(currentProductObject);

                    product.link = pinterestHelpers.getLink(currentProductObject, hostName);

Using inheritance with an Object oriented structure seems logical at first, but since we are working with javascript, I would like to implement it if there is a simpler way by sacrificing object oriented.
