## Description
|
|||
|
|
<section id="description">现在您已经开始编写JSX了，您可能想知道它与HTML的区别。到目前为止，似乎HTML和JSX完全相同。 JSX的一个关键区别是你不能再使用单词<code>class</code>来定义HTML类。这是因为<code>class</code>是JavaScript中的保留字。相反，JSX使用<code>className</code> 。事实上，JSX中所有HTML属性和事件引用的命名约定都变成了camelCase。例如，JSX中的单击事件是<code>onClick</code> ，而不是<code>onclick</code> 。同样， <code>onchange</code>变为<code>onChange</code> 。虽然这是一个微妙的差异，但重要的是要记住前进。 </section>
