 <p> 静态<code><strong>ArrayBuf</strong></code><strong>fer.transfer()</strong> 方法返回一个新的ArrayBuffer， 其内容取自oldBuffer的数据，并且根据 newByteLength 的大小来对数据进行截取或者以0扩展。 如果 newByteLength 未定义，则使用 oldBuffer 的byteLength。这个操作使得 oldBuffer 处于被移除的状态。</p>

 <p><code>ArrayBuffer.transfer()</code>方法允许你增长和移除 <code>ArrayBuffer</code> 对象。不需复制就能增长一个ArrayBuffer的功能，对于大的缓冲区来说，有速度优势 (类似realloc) 。当释放底层内存时，移除ArrayBuffer的功能给开发者提供了显式控制。这避免了必须丢弃所有引用和等待垃圾回收。</p>
