/* setting up a web component will extend the set of available HTML elements for you to use in your
project and keep your codebase organized and modular. Set up a web component in a separate file 
and link it directly in your html document head. 

creating a custom web component is just like creating a class. after setting up 
the constructor function, you need to create some methods that tell the browser more about it. 
you can add whatever methods you want, but they at least need some of the following:

1) connectedCallback() => call this method when the element is added to the document, 
2) disconnectedCallback() => call this method when the element is removed from the document
3) static get observedAttributes() => this returns an array of attribute names to track for changes
4) attributeChangedCallback(name, oldValue, newValue) => this one is called when one of the attributes 
5) adoptedCallback() => called when the element is moved to a new document
