SessionStorage and localStorage in javascript, simple database
14.09.23
## sessionStorage is similar to localStorage; the difference is that while data in localStorage doesn't expire, data in sessionStorage is cleared when the page session ends. ```javascript // Save data to sessionStorage sessionStorage.setItem("key", "value"); // Get saved data from sessionStorage let data = sessionStorage.getItem("key"); // Remove saved data from sessionStorage sessionStorage.removeItem("key"); // Remove all saved data from sessionStorage sessionStorage.clear(); //Save more complex data sessionStorage.setItem(objectname, JSON.stringify(object)); ``` ## is similar to sessionStorage, except that while localStorage data has no expiration time ```javascript localStorage.setItem("myCat", "Tom"); const cat = localStorage.getItem("myCat"); localStorage.removeItem("myCat"); localStorage.clear(); ```
