(JavaScript) DynamoDB - ListTables
Returns an array of table names associated with the current account and endpoint. The output from ListTables is paginated, with each page returning a maximum of 100 table names. For more information, see https://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_ListTables.html
