const AWS = require('aws-sdk');
const dynamodb = new AWS.DynamoDB();

const params = {
  TableName: 'YourTableName',
  Item: {

    'nestedDocument': {
      M: {
        'name': { S: 'John' },
        'age': { N: '30' },

dynamodb.putItem(params, (err, data) => {
  if (err) {
    console.error('Error:', err);
  } else {
    console.log('Item inserted successfully:', data);
