The logical OR operator

The logical OR operator returns true if either of the operands are true.

Here is a prototype:

varA || varB 

Here is a example:

var x = true  
var y = false 
var z = x || y  //z equals true 

For those who are familiar with the C language, or similar languages, these operators should look pretty familiar. For those of you who aren't that familiar with the C operators, rest assured that, once you begin to use them frequently, they will become second nature.
