Too Long; Didn't Read
In this tutorial, we are going to see how to create a mutable state by using a writable object. The project is going to be a simple page where you can add contacts into a list of contacts. We will use a store object, subscribe to it, add new entries and reset its value. This component will show all contacts and update automatically, but it’s better to use $ as prefix to contacts. In this way, Svelte will manage subscription automatically.
