HTML Tables; JS Constructor Functions
HTML Tables:
  - The 
<table> element is used to add tables to a web page. 
  - A table is drawn out row by row. Each row is created with the 
<tr> element. 
  - Inside each row there are a number of cells represented by the 
<td> element (or <th> if it is a header). 
  - You can make cells of a table span more than one row or column using the rowspan and colspan attributes.
 
  - For long tables you can split the table into a 
<thead>, <tbody>, and <tfoot>. 
JS Constructor Functions:
  - An object is a series of variables and functions that represent something from the world around you.
 
  - In an object, variables are known as properties of the object; functions are known as methods of the object.
 
  - Web browsers implement objects that represent both the browser window and the document loaded into the browser window.
 
  - JavaScript also has several built-in objects such as String, Number, Math, and Date. Their properties and methods offer functionality that help you write scripts.
 
  - Arrays and objects can be used to create complex data sets (and both can contain the other).
