Retrieves the remaining memory space, in bytes, for the storage object.
Each Storage object provides access to a list of key/value pairs, which are sometimes called items. Keys are strings, and any string (including the empty string) is a valid key. Items contain values (which are also strings) and associated metadata.
Each Storage object is associated with a list of key/value pairs when it is created. Multiple Storage objects, such as two instances of localStorage, can be associated with the same list of key/value pairs simultaneously.
Key names are exposed as properties on this object. For example, the following statements are equivalent:
sessionStorage.setItem('myKey', '...'); sessionStorage['myKey'] = '...'; sessionStorage.myKey = '...';
