how to using where in node.js to get data 
from firestore with dependencies firebase version 9.21.0

import { initializeApp } from 'firebase/app';
import { getFirestore, collection, query, where, getDocs } from 'firebase/firestore';

// Initialize Firebase
const firebaseConfig = {
  // Add your Firebase configuration object here
  // apiKey: "...",
  // authDomain: "...",
  // projectId: "...",
  // ...
};

const app = initializeApp(firebaseConfig);
const db = getFirestore();

// Function to query data from Firestore
async function queryData(collectionName, field, operator, value) {
  try {
    const collectionRef = collection(db, collectionName);
    const q = query(collectionRef, where(field, operator, value));
    const querySnapshot = await getDocs(q);

    querySnapshot.forEach((doc) => {
      console.log('Document ID:', doc.id);
      console.log('Document data:', doc.data());
    });
  } catch (error) {
    console.error('Error querying data:', error);
  }
}

// Call the function with the desired collection name and query parameters
const collectionName = 'yourCollectionName';
const field = 'yourField';
const operator = '=='; // Can be '==', '>', '<', '>=', '<=', 'array-contains', etc.
const value = 'yourValue';
queryData(collectionName, field, operator, value);
