ArrayBuffer.prototype.resizable
The resizable
accessor property of ArrayBuffer
instances returns whether this array buffer can be resized or not.
Try it
Description
The resizable
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. If the maxByteLength
option was set in the constructor, resizable
will return true
; if not, it will return false
.
Examples
Using resizable
In this example, we create a 8-byte buffer that is resizable to a max length of 16 bytes, then check its resizable
property, resizing it if resizable
returns true
:
js
const buffer = new ArrayBuffer(8, { maxByteLength: 16 });
if (buffer.resizable) {
console.log("Buffer is resizable!");
buffer.resize(12);
}
