Sometimes the space around something can assist in the understanding of something as much as the thing itself. This is generally referred to as whitespace. Whitespace is useful since it separates different things from one another.

Quick Example

Consider the following code fragment:

Fatal error: Uncaught Error: Class 'format' not found in /home/abentley/www/pages/pgm101/ws.html:19 Stack trace: #0 /home/abentley/_framework/library/framework.php(126): include() #1 /home/abentley/_framework/library/framework.php(60): FRAMEWORK::include_file() #2 /home/abentley/_framework/library/framework.php(1466): FRAMEWORK::respond() #3 /home/abentley/public_html/index.php(4): include_once('/home/abentley/...') #4 {main} thrown in /home/abentley/www/pages/pgm101/ws.html on line 19
