  • Well-designed API signatures
  • Easy connections / configuration
  • Command buffering. You can start querying right away
  • Promises built-in for all queries. Easy interoperability with modules
  • Auto-casting of _id in queries
  • Allows to set global options or collection-level options for queries. (eg: castIds is true by default for all queries)
