IDBFactory
The IDBFactory interface of the IndexedDB API lets applications asynchronously access the indexed databases. The object that implements the interface is window.indexedDB. You open — that is, create and access — and delete a database with the object and not directly with IDBFactory. see IDBFactory on MDN

Value members
Concrete methods
Compares two values as keys to determine equality and ordering for IndexedDB operations, such as storing and iterating.

- Returns:
One of the following:
-1means 1st key is less than the 2nd key0means 1st key is equal to the 2nd key1means 1st key is greater than the 2nd key
Returns a promise which resolves to a list of objects giving a snapshot of the names and versions of databases within the origin.

This API is intended for web applications to introspect the use of databases, for example to clean up from earlier versions of a site’s code. Note that the result is a snapshot; there are no guarantees about the sequencing of the collection of the data or the delivery of the response with respect to requests to create, upgrade, or delete databases by this context or others.
The deletion operation (performed in a different thread) consists of the following steps:
The deletion operation (performed in a different thread) consists of the following steps:
The open() method of the IDBFactory interface requests opening a connection to a database. see IDBFactory.open() on MDN
