Using code You can store the value in localStorage with the key value pair. It has two methods setItem(key, value) to store the value in the storage object and getItem(key) to retrieve the value from the storage object.
If you want to store two different values in localStorage then you can do somrthing like this : setItem in localStorage two times with different keys. localStorage. setItem("message", taskMessage); localStorage.
Any content/data saved to the localStorage object will be available after the browser has been restarted (closed and opened again). In order to save an item to localStorage , you can use the method setItem() . This method must be handed a key and a value.
The array becomes a string and you can save it into your browser's local storage.

Regarding browsers, here is a list,
Firefox 3.5, Safari 4, IE8, Chrome 4+: HTML5 localStorage; these modern browsers all support the core localStorage functionality defined in the HTML5 draft.
Firefox 2.x and 3.0: Gecko globalStorage, a very early implementation similar to HTML5’s localStorage.
Safari 3.1 & 3.2: HTML5 Database Storage, because Safari 3.1 and 3.2 don’t support HTML5 localStorage.
IE6, IE7: userData persistence, a rarely used IE feature for associating string data with an element on a web page and persisting it between pageviews.
Google Chrome Pre 4: Gears Database API, which is built into earlier versions of Chrome and thus doesn’t require a separate install.
Here is alist of browsers that support this functionality. https://stackoverflow.com/questions/1194784/which-browsers-support-html5-offline-storage
There is no limit for the number of variables, a detailed explanation for using HTML5 local storage can be found here
