20 - When would you use a conditional, loop, object manipulation, comment, and exception statement (statements) ? Conditional statements are used to control your scripts so that different actions can be taken depending on the situation. A loop statement checks to see if some condition is true, say our condition is "Are there any invitations left?" and if that condition is true it will execute a chunk of code. These are statements that are used to take advantage of the object model to get tasks done. Comment statements are used to prevent the browser from executing certain parts of code that you designate as non-code. The Exception statement tries to execute a piece of code and if it fails the catch should handle the error gracefully.
