The maxByteLength
accessor property of ArrayBuffer
instances returns the maximum length (in bytes) that this array buffer can be resized to.
The maxByteLength
accessor property of ArrayBuffer
instances returns the maximum length (in bytes) that this array buffer can be resized to.
The maxByteLength
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, set via the maxByteLength
option of the ArrayBuffer()
constructor, and cannot be changed.
This property returns 0 if this ArrayBuffer
has been detached. If this ArrayBuffer
was constructed without specifying a maxByteLength
value, this property returns a value equal to the value of the ArrayBuffer
's byteLength
.
In this example, we create an 8-byte buffer that is resizable to a max length of 16 bytes, then return its maxByteLength
:
const buffer = new ArrayBuffer(8, { maxByteLength: 16 }); buffer.maxByteLength; // 16
