remove multiple index from array mongodb

Comment

const mongoose = require('mongoose');

// Define your schema
const mySchema = new mongoose.Schema({
  myArray: [String] // Replace "String" with the actual type of the elements in your array
});

// Create your model
const MyModel = mongoose.model('MyModel', mySchema);

// Remove multiple items from the array by indexes using a MongoDB query
const removeItemsByIndexes = async (documentId, indexes) => {
  try {
    const updateOperations = indexes.map((index) => ({ $pull: { myArray: { $eq: index } } }));
    await MyModel.updateOne({ _id: documentId }, updateOperations);
    console.log('Items removed successfully.');
  } catch (error) {
    console.error(error);
  }
};

// Usage
removeItemsByIndexes('documentId', [2, 4, 6]); // Replace 'documentId' with the actual ID of the document and [2, 4, 6] with the indexes of the items you want to remove
