 <p>上面的代码创建了三个新的symbol类型。 注意，<code>Symbol("foo")</code> 不会强制将字符串 “foo” 转换成symbol类型。它每次都会创建一个新的 symbol类型：</p>

 <p>这会阻止创建一个显式的 Symbol 包装器对象而不是一个 Symbol 值。围绕原始数据类型创建一个显式包装器对象从 ECMAScript 6 开始不再被支持。 然而，现有的原始包装器对象，如 <code style="font-style: normal;">new Boolean</code>、<code style="font-style: normal;">new String</code>以及<code>new Number</code>，因为遗留原因仍可被创建。</p>
 
 <p>如果你真的想创建一个 <u>Symbol 包装器对象 </u>(<code>Symbol wrapper object</code>)，你可以使用 <code>Object()</code> 函数：</p>
