# Browser local storage in JavaScript

The browser has a so-called local storage that allows you to store data between user visits to the site (`5`-`10` megabytes of information).

Data is accessed by a key: you store data with some key, and then you can retrieve it by that key or delete it. It is allowed to save only strings. There are special methods for working with data. Let's consider them.

Two types of storages are used for data storage: `sessionStorage` and `localStorage`. The first stores data only until the browser is closed, and the second always.

In the next lessons we will deal with the possibilities of the local storage.
