JavaScript Conditions Using || and && short circuiting
Example
The Boolean operators || and && will "short circuit" and not evaluate the second parameter if the first is true or false respectively. This can be used to write short conditionals like:
var x = 10
x == 10 && alert("x is 10")
x == 10 || alert("x is not 10")
