Storage
This Web Storage API interface provides access to a particular domain's session or local storage. It allows, for example, the addition, modification, or deletion of stored data items.

[name: string]: any
Properties
readonly length: number
Returns the number of key/value pairs currently present in the list associated with the object.
Methods
clear(): void
Empties the list associated with the object of all key/value pairs, if there are any.
getItem(key: string): string | null
Returns the current value associated with the given key, or null if the given key does not exist in the list associated with the object.
key(index: number): string | null
Returns the name of the nth key in the list, or null if n is greater than or equal to the number of key/value pairs in the object.
removeItem(key: string): void
Removes the key/value pair with the given key from the list associated with the object, if a key/value pair with the given key exists.
setItem(key: string, value: string): void
Sets the value of the pair identified by key to value, creating a new key/value pair if none existed for key previously.
Throws a "QuotaExceededError" DOMException exception if the new value couldn't be set. (Setting could fail if, e.g., the user has disabled storage for the site, or if the quota has been exceeded.)
