<p><strong><code>InternalError</code> 对象</strong>表示出现在JavaScript引擎内部的错误。 例如： <strong>"InternalError</strong>: too much recursion"（内部错误：递归过深）。</p>

<p>当JavaScript引擎出现内部错误时将会抛出<code>InternalError。</code></p>
<p>示例场景通常为某些成分过大，例如：</p>
<ul>
<li>"too many switch cases"（过多<code>case</code>子句）；</li>
<li>"too many parentheses in regular expression"（正则表达式中括号过多）；</li>
<li>"array initializer too large"（数组初始化器过大）；</li>
<li>"too much recursion"（递归过深）。</li>
</ul>
