ArrayBuffer.prototype.resizable

¥Description

resizable 属性是一个访问器属性，其设置的访问器函数为 undefined，这意味着你只能读取该属性。该值是在构造数组时确定的。如果在构造函数中设置了 maxByteLength 选项，则 resizable 将返回 true；如果不是，则返回 false。

¥The resizable property is an accessor property whose set accessor function is undefined, meaning that you can only read this property. The value is established when the array is constructed. If the maxByteLength option was set in the constructor, resizable will return true; if not, it will return false.

¥Examples

¥Using resizable

在此示例中，我们创建一个 8 字节缓冲区，最大长度可调整为 16 字节，然后检查其 resizable 属性，如果 resizable 返回 true 则调整其大小：

¥In this example, we create a 8-byte buffer that is resizable to a max length of 16 bytes, then check its resizable property, resizing it if resizable returns true:

const buffer = new ArrayBuffer(8, { maxByteLength: 16 });

if (buffer.resizable) {
  console.log("Buffer is resizable!");
  buffer.resize(12);
}
