## Description
|
|||
|
|
<section id="description">订单在<code>if</code> ， <code>else if</code>语句中很重要。该函数从上到下执行，因此您需要注意首先出现的语句。以这两个函数为例。这是第一个： <blockquote> function foo（x）{ <br> if（x <1）{ <br>返回“少于一个”; <br> } else if（x <2）{ <br>返回“少于两个”; <br> } else { <br>返回“大于或等于2”; <br> } <br> } </blockquote>第二个只是切换语句的顺序： <blockquote>功能栏（x）{ <br> if（x <2）{ <br>返回“少于两个”; <br> } else if（x <1）{ <br>返回“少于一个”; <br> } else { <br>返回“大于或等于2”; <br> } <br> } </blockquote>虽然如果我们将数字传递给两者，这两个函数看起来几乎相同但我们得到不同的输出。 <blockquote> foo（0）//“不到一个” <br> bar（0）//“少于两个” </blockquote></section>
