Using async/await

Rather than using promises, you should consider using async/await. Async functions are simpler and take less boilerplate than using promises. Await can only be used in an async function to asynchronously wait for a value.

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

import { DynamoDBClient, 
ListTablesCommand } from "@aws-sdk/client-dynamodb";
(async function () {
    const dbClient = new DynamoDBClient({ region: "us-west-2" });
    const command = new ListTablesCommand({});

    try {
        const results = await dbClient.send(command);
        console.log(results.TableNames.join('\n'));
    } catch (err) {
        console.error(err)
    }
})();
