CODE EXAMPLE FOR JAVASCRIPT

mongoose model find all documents with ids in array

const ids =  [
    '4ed3ede8844f0f351100000c',
    '4ed3f117a844e0471100000d', 
    '4ed3f18132f50c491100000e',
];

// 3 Methods below:
// Using Mongoose with async function:
const records = await Model.find().where('_id').in(ids).exec();

// Or more concise:
const records = await Model.find({ '_id': { $in: ids } });

// Using Mongoose with callback:
Model.find().where('_id').in(ids).exec((err, records) => {});
