title: Add multiple values to dynamoDB
body: <p>I want to add multiple values to DynamoDB. I want to add all the sets of data. </p>
  
  <p>For example, If 4 values, then 4 rows I want to add in DynamoDB. For 'n' number of receiving values, 'n' rows of them should be added. </p>
  
  <p>I looped through arrays but still only latest data is set into <em>item</em> and I am able to save only one row. i.e., the last value of every arrays. </p>
  
  <p>How can I achieve this. Please help me.</p>
