本文开始学习if语句，和大部分语言一样，JavaScript 中if语句，基本格式如下：

if（条件为真）{

代码块；

}

<! DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
</head>
<body>
<script type ="text/javascript">
		var apples = 35;
		var hotdogs = 76;
		if (apples < hotdogs){
			document.write("yea it worked!");
		}
</script>
</body>
</html>

自己修改下数字大小，还有以下条件，测试运行看看。

apples == hotdogs

apples != hotdogs

apples > hotdogs

apples >= hotdogs

apples <= hotdogs
