&& and || as conditional statements

suggest change

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")
