title: Overlapping Rectangles Javascript
body: <p>I need to write an function that takes Rectangles and determines the overlapping area in between them.
  The format in which the array is shown is the following:</p>
  
  <p>["(0,0),(2,2),(2,0),(0,2),(1,0),(1,2),(6,0),(6,2)"]</p>
  
  <p>The first four points define the first rectangle and the second four define the second.</p>
  
  <p>I have been able to split and parseInt the coordinates, but I am having difficulty on how to find the overlapping area. Thank you!</p>
