javascript - HTML5 Local storage vs. Session storage

itemprop="text">

Apart from being non
persistent and scoped only to the current window, are there any benefits (performance,
data access, etc) to Session Storage over Local Storage?

Answer

href="https://developer.mozilla.org/en-US/docs/Web/API/Window/localStorage"
rel="noreferrer">localStorage and href="https://developer.mozilla.org/en-US/docs/Web/API/Window/sessionStorage"
rel="noreferrer">sessionStorage both extend href="https://developer.mozilla.org/en-US/docs/Web/API/Storage"
rel="noreferrer">Storage. There is no difference between them except for
the intended "non-persistence" of
sessionStorage.

That
is, the data stored in localStorage persists until explicitly
deleted. Changes made are saved and available for all current and future visits to the
site.

For
sessionStorage, changes are only available per tab. Changes
made are saved and available for the current page in that
tab until it is closed. Once it is closed, the stored data is
deleted.
