 /**
- * IndexDB version must be a integer
- * @returns
+ * IndexDB prefers incremental versioning when upgrading the database,
+ * otherwise it may throw an error, and we need to destroy the database
+ * and recreate it.
+ * To calculate the version number, we use the following formula,
+ * assuring incremental versioning:
+ *   version = major * 1000000 + minor * 1000 + patch
+ * ex:
+ *  - version 1.2.3 => 1002003
+ *  - version 0.10.15 => 10015
+ *  - version 2.0.0 => 2000000
+ * @returns number
