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.
A key range can have a single value or a range with upper and lower bounds or endpoints. If the key range has both upper and lower bounds, then it is bounded; if it has no bounds, it is unbounded. A bounded key range can either be open (the endpoints are excluded) or closed (the endpoints are included). To retrieve all keys within a certain range, you can use the following code constructs:
- Companion:
- object

Concrete methods
The lower bound of the key range (can be any type.)
The lower bound of the key range (can be any type.)
Returns false if the lower-bound value is included in the key range.
Returns false if the lower-bound value is included in the key range.
The upper bound of the key range (can be any type.)
The upper bound of the key range (can be any type.)
