A Little Interaction: Event, Handlers, and etc (Notes)

For every event that occurs using your code you can manipulate/handle the event to cause various actions to occur
To handle events for an object we need a reference for it. This can be done using document.getElementById("object")
After making a referece to the object we can modify its properties to commit actions, for example: object.onclick = myfunction
We can use document.createElemement("element") to create new elements using Javascript. Setting this newly created element to a variable allows us to further manipulate the DOM.
parent.appendChild(var) appends the var element to the parent element
