ArrayBuffer.prototype.detached
Baseline 2024
Newly available
Since March 2024, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.
The detached
accessor property of ArrayBuffer
instances returns a boolean indicating whether or not this buffer has been detached (transferred).
Description
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
js
const buffer = new ArrayBuffer(8);
console.log(buffer.detached); // false
const newBuffer = buffer.transfer();
console.log(buffer.detached); // true
console.log(newBuffer.detached); // false
