The indexedDB deleteDatabase() method is used to request the deletion of a database. The method returns an IDBOpenDBRequest object immediately and performs the deletion operation asynchronously.
Syntax:
var request = indexedDB.deleteDatabase(name);
Parameters:
- name: The name of the database you want to delete.
Return value: A IDBOpenDBRequest object after deletion.
Example: In this example, we will open a database and hence, will delete that database using this method.
