 4 | AWS SDK for JavaScript v2.1.33
 5 | 
 6 | While it's true, Amazon provides detailed documentation for DynamoDB, unfortunately the code snippets are incomplete, inconsistent and may contain errors. In the spirit of cutting through the confusion, here's a really simple DynamoDB example, that actually works.
 7 | 
 8 | Switch out the keys for your own.
 9 | 
10 | This is a demo only. Don't hardcode secret keys in javascript.
11 | 
12 | Review the screenshots for several AWS gotcha's.
