ArrayBuffer.prototype.detached
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
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
