The localStorage API

In most applications, we have some form of data management that presents data in tables so that table rows correspond to objects and the table schema corresponds to the objects’ type. When building a front-end web application with JS, the simplest way to get persistent data storage is to use the localStorage API.

However, while the localStorage API provides a simple key-value database it doesn’t support database tables. So, the question is, how can we store and retrieve tables with localStorage? To do this, we’ll need to learn to represent database tables in the form of entity tables. Then, we’ll learn to store those tables in localStorage.
