<p>语法错误（<a href="Reference/Global_Objects/SyntaxError" title="SyntaxError 对象代表尝试解析语法上不合法的代码的错误。"><code>SyntaxError</code></a> ），只出现于<a href="/en-US/docs/Web/JavaScript/Reference/Strict_mode">严格模式</a>下。</p>
<h2 id="哪里出错了？">哪里出错了？</h2>
<p>八进制字面量与八进制转义序列语法已经被废弃，在严格模式下会报语法错误（<a href="Reference/Global_Objects/SyntaxError" title="SyntaxError 对象代表尝试解析语法上不合法的代码的错误。"><code>SyntaxError</code></a>）。在 ECMAScript 2015 及以后的规范中，标准语法是前导 0 后面跟一个大写或小写的拉丁文字母 "O" (<code>0o</code> 或 <code>0O)。</code></p>
