Global Variable Is Not Updating Using Nodejs

I have below global variable and trying to update in diffrent methods var companyName; In this method i am getting company name and can able to print the companyName in terminal v

Solution 1:

try to change this:

once(myDB);

console.log('Company inside db call :' + companyName);

to :

once(myDB).then(v=>console.log('Company inside db call :' + companyName)).catch(v=>console.log('error',v))

because once(myDB) is async and returns a promise you can put the callback in the promise.then(v=>/*your callback*/)
