IDBCursor class

Note: Not to be confused with IDBCursorWithValue which is just an interface with an additional value property.

The interface of the IndexedDB API represents a cursor for traversing or iterating over multiple records in a database. The cursor has a source that indicates which index or object store it is iterating over. It has a position within the range, and moves in a direction that is increasing or decreasing in the order of record keys. The cursor enables an application to asynchronously process all the records in the cursor's range. You can have an unlimited number of cursors at the same time. You always get the same object representing a given cursor. Operations are performed on the underlying index or object store. Note: This feature is available in Web Workers
