如何重构此代码以从数组中获取Mongo数据？

Question

let arrayOfDocuments = await Promise.all(result.data.CompanyCodes.map(async (eachCompany) => {
  let corporate = await Organization.findOne({ codeOfCompany: eachCompany });
  return corporate;
}));

I would like to know if there's a better way to refactor the above code.

Please try with $in in Mongo Query:

let arrayOfDocuments = await Organization.find({ 
    codeOfCompany: { '$in': result.data.CompanyCodes }
})

Document here https://docs.mongodb.com/manual/reference/operator/query/in/ . This query check if field codeOfCompany is exist in array of values result.data.CompanyCodes .
