Shortcut for if-else in JavaScript

JavaScript has C-like syntax. Therefore, it is possible to use the ?: conditional operator, which is a shortcut for the if-else block:
Expression?true part:false part
Try this example:
<script language=javascript>
function foo(){
	(1<2)?alert("1 is less than 2"):alert("1 is not less than 2");
!(1<2)?alert("1 is less than 2"):alert("1 is not less than 2");
<input type=button value="click" onclick="foo()">
