How do I write data to a file with Javascript?

I made a game with javascript using this tutorial as a base: http://html5gamedev.samlancashire.com/making-a-simple-html5-canvas-game-part-3-drawing-images/ How do I get it to write the data from the item counter (var itemCounter = 50;) to a text file named savedata.txt? I googled it, but no helpful results came up. Can someone help me?

Writing a file is posible with the new FileWriter and FileSystem APIs.

More mature solutions (not using files) have already been mentioned

Its not possible to store the data as a file on the client. But you can use localstorage, websql, indexeddb or simply cookies for it. Note that all of these storages have different properties in terms of lifetime.

You could also create a blob using the blobapi and then create a dataurl and request the user to save it, using drag and drop + fileapi to read the data, this approach however will make it easy for users to modify the data.
