ArrayBuffer.prototype.detached

¥Description

detached 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。第一次创建 ArrayBuffer 时，值为 false。如果 ArrayBuffer 是 transferred，则该值将变为 true，这会将实例与其底层内存分离。一旦缓冲区分离，它就不再可用。

¥The detached property is an accessor property whose set accessor function is undefined, meaning that you can only read this property. The value is false when the ArrayBuffer is first created. The value becomes true if the ArrayBuffer is transferred, which detaches the instance from its underlying memory. Once a buffer becomes detached, it is no longer usable.

¥Examples

¥Using detached

const buffer = new ArrayBuffer(8);
console.log(buffer.detached); // false
const newBuffer = buffer.transfer();
console.log(buffer.detached); // true
console.log(newBuffer.detached); // false
