While date/time information items have to be formated as strings in a human-readable form on web pages, preferably in localized form based on the settings of the user's browser, it's not a good idea to store date/time values in this form. Rather we use instances of the pre-defined JavaScript class Date for representing and storing date/time values.

In most apps we have some form of data management where data is represented in tables such that table rows correspond to objects, anf the table schema corresponds to the objects' type. When building a front-end web app with JavaScript, the simplest approach for persistent data storage is using JavaScript's localStorage API, which provides a simple key-value database, but does not support database tables. So, the question is: how can we store and retrieve tables with Local Storage?

In standard OO, as defined by UML, and instantiated by Java, there is a certain concept of object. What's the difference between this classical concept of objects and a JavaScript object?
