Node.js and Cassandra: Improved Javascript Type Support

The new version of DataStax Node.js Driver for Apache Cassandra introduces improved data type support in JavaScript, including types not available in the Ecmascript standard. It also adds support for ES 6 Map/Set built-in types and introduces support for batches of prepared statements and named parameters for prepared statements. The driver now uses its own BigDecimal representation for Cassandra decimal support and Google Closure Integer for varint, as well as rolling out its own Uuid and TimeUuid classes. These enhancements aim to make working with Cassandra data types easier and more efficient.
