title: DynamoDB Array of String becomes Array of Objects
body: <p>I insert an array of string to DynamoDB:</p>
  
  <pre><code>[13, 12, 12, 4]
  </code></pre>
  
  <p>It becomes Array of Objects when I view it in DynamoDB:</p>
  
  <pre><code>[ { "S" : "13" }, { "S" : "12" }, { "S" : "12" }, { "S" : "4" }]
  </code></pre>
  
  <p>Is it reasonable? Do I need to do something to make my data being inserted as array of string?</p>
  
  <p>Here is how I put my array to DynamoDB:</p>
  
  <pre><code>var params = {
     TableName: "MatchDate",
     Item:{
        position: [1, 3, 4, 5]
     }
  };
  
  DynamoDBClient.put(params, function(err, data) {
     //Some other code
  });
  </code></pre>
