HTML DOM indexedDB deleteDatabase() Method

Last Updated : 19 Jul, 2020

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.
