/**
  * The IDBKeyRange interface of the IndexedDB API represents a continuous interval over some data type that is used for keys. Records can be retrieved from object stores and indexes using keys or a range of keys. You can limit the range using lower and upper bounds. For example, you can iterate over all values of a key between x and y.
