Call a function on each object in an array in Node

Question

I'm trying to batch together a database update to re-populate a mongo collection. I've created an object to hold the properties needed to lookup the data from an external source, and then add it back to a MongoDb collection.

The array looks like this:

const pops = [ 
    { table: 'SFAccounts',
      label: 'Account__c', 
      createListName: 'Accounts'
    },
    { table: 'SFTimes',
      label: 'CusTime__c', 
      createListName: 'Time'
    }]

I want to then create a function that takes 'table', 'label, and 'createListName' and it does something basically like this..

async function processData(table, label, createListName) {
    // Get some info from Salesforce 
    const dataFromSF = await getMetaDataFromSalesForce(table)
    // Extract the parts I actually need
    const relevantBits = dataFromSF.filter(field => field.name === label)
    //Create a new list in the db
    const createResult = await List.create( { name: createListName, values: relevantBits } )
    return createResult
}

The end goal is to get to something like

await Promise.all(processData(pops))

Which will await all the tables being pulled and populated into the database.

If you change the args of processData:

async function processData({table, label, createListName}) {
    // Get some info from Salesforce 
    const dataFromSF = await getMetaDataFromSalesForce(table)
    // Extract the parts I actually need
    const relevantBits = dataFromSF.filter(field => field.name === label)
    //Create a new list in the db
    const createResult = await List.create( { name: createListName, values: relevantBits } )
    return createResult
}

it's just await Promise.all(pops.map(processData));
