The AWS SDK for JavaScript v2 has reached end-of-support. We recommend that you migrate to [AWS SDK for JavaScript v3](https://docs.aws.amazon.com//sdk-for-javascript/v3/developer-guide/). For additional details and information on how to migrate, please refer to this [announcement](https://aws.amazon.com/blogs//developer/announcing-end-of-support-for-aws-sdk-for-javascript-v2/).

# Using async/await
<a name="using-async-await"></a>

You can use the `async/await` pattern in your calls to the AWS SDK for JavaScript. Most functions that take a callback do not return a promise. Since you only use `await` functions that return a promise, to use the `async/await` pattern you need to chain the `.promise()` method to the end of your call, and remove the callback.

The following example uses async/await to list all of your Amazon DynamoDB tables in `us-west-2`.

```
var AWS = require("aws-sdk");
//Create an Amazon DynamoDB client service object.
dbClient = new AWS.DynamoDB({ region: "us-west-2" });
// Call DynamoDB to list existing tables
const run = async () => {
  try {
    const results = await dbClient.listTables({}).promise();
    console.log(results.TableNames.join("\n"));
  } catch (err) {
    console.error(err);
  }
};
run();
```

**Note**  
 Not all browsers support async/await. See [Async functions](https://caniuse.com/#feat=async-functions) for a list of browsers with async/await support.
