During development, it is often necessary to have blocks of code for debugpurposes. If the debug code is lengthy, commenting anduncommenting it can be tedious. But if you put either a ‘–‘ in front of each lineor a ‘/*’ at the front and a ‘*/’ at the end of each line, you can comment and uncomment the code block with a couple of keystrokes. Here are examples of each method:

Commented code

 /* Debug code goes in this blockPrint 'Some debug info'Print 'Some more debug info'--*/

Uncommented code

 --/* Debug code goes in this blockPrint 'Some debug info'Print 'Some more debug info'--*/

Just by adding or deleting two dashes at the beginning of the code block, theentire block can be commented or uncommented.
