Javascript global variable not updating

October 24, 2022

I am trying to access the dataCount variable from another file after its been updated by updateData function which takes an array as a parameter and as the pop function returns the new length I have passed that directly to the updateStatus function.
But even after updating it and accessing it stills gives me 0.

// status.js file

var dataCount = 0;
let data = []

function updateStatus(num, opp){
    if (opp == "add"){
        dataCount += num
    } else if (opp == "sub") {
        dataCount -= num
    } else {
        dataCount = num;
    }
}

function updateData(arr){
    updateStatus(data.push(arr), 'update');
}

module.exports = {
    dataCount: dataCount,
    updateStatus: updateStatus,
    data: data,
    updateData: updateData
}

// middleware.js file

const status = require('./status');
const methods = require('./helperFunctions')

class Middleware{
    constructor(){
    }

    async populateIfLess(req, res, next){
        if (status.dataCount < 4){
            try {
                // Fetches the data from database and stores in data
                const data = await methods.fetchMeaning();
                Object.entries(data).map(entry => {
                    status.updateData([entry[0], entry[1]])
                })
                methods.log('Data populated on')
                setTimeout(() => {
                    console.log(status.dataCount)
                }, 1500);
                next()
            } catch (error) {
                methods.log(error);
                res.send({ERROR: "Something went wrong, please check log file."}).end()
            }
        }
    }
}
