The byteLength
accessor property represents the length of an ArrayBuffer
in bytes.
arraybuffer.byteLength
The byteLength
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 and cannot be changed. This property returns 0 if this ArrayBuffer
has been detached.
var buffer = new ArrayBuffer(8); buffer.byteLength; // 8
