Version
In centralized environments, we can use linear version numbers to represent a version, such as incrementing a number each time or using timestamps. However, CRDTs can be used in decentralized environments, and their version representation is different.
In Loro, you can express a document's version through a Version Vector (opens in a new tab) or Frontiers.
doc.version(); // Version vector
doc.frontiers(); // Frontiers
In most cases, you might only need the Version Vector, which can be used for data synchronization and version comparison.
To understand the difference and the definition of Frontiers
