title: Put item on DynamoDB table using AWS SDK for Node.js
body: <p>I'm new to javascript and node.js and was wondering if someone can help me figure out the syntax of putting a new item onto an existing table on AWS Dynamodb through their node.js SDK. Here's what I have so far. Is there an example for what I'm trying to do? If anyone could point me in the right direction, it'd be much appreciated. </p>
  
  <pre><code>var AWS = require('aws-sdk');
  AWS.config.loadFromPath('./config.json');
  AWS.config.update({region: 'us-east-1'});
  var dynamodb = new AWS.DynamoDB();
  
  var item = {
      // I need to put the an item with a the primary key of "id", and an attribute called "item"
      // I'm new to js and node.js, so if somebody could help me understand the documentation
      // http://docs.aws.amazon.com/AWSJavaScriptSDK/latest/frames.html#!http%3A//docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/DynamoDB_20120810.html
  }
  
  dynamodb.putItem({TableName: 'log_dev', Item: item}, function(err, data){
      if (err) {
      console.log(err); // an error occurred
      } else {
      console.log(data); // successful response
      }
  });
  </code></pre>
