This is my code:

Answer 1

Here is the correct way to do it:

function batchWrite(arrayOf25) {

 //25 is as many as you can write in one time

  var itemsArray = [];

  for (i = 0; i < arrayOf25.length; i++) {

    var someItem = arrayOf25[i];
    var item = {
                PutRequest: {
                 Item: someItem
                }
             };


    if (item) {
      itemsArray.push(item);
    }

 }


  var params = {
      RequestItems: { 
        'my_table_name': itemsArray
      }
    };

    //var AWS = require('aws-sdk'); //These should be added at the top
    //var docClient = new AWS.DynamoDB.DocumentClient({region: 'us-east-1'});

    docClient.batchWrite(params, function(err, data) {

      if (err) {
          console.log(err); 
      } 
      else  {

          console.log('Added ' + itemsArray.length + ' items to DynamoDB');

      }   


    });
