JavaScript ArrayBuffer resizable Property

JavaScript resizable property in ArrayBuffer is used to check whether an ArrayBuffer can be resized or not. It returns a boolean value. It is a read-only property whose value is set when maxByteLength is defined.

Syntax:

arr.resizable

Parameters: It does not accept any parameter.

Example 1: In this example, we will check if the ArrayBuffers are resizable.

let arr1 = new ArrayBuffer(8); let arr2 = new ArrayBuffer(8, { maxByteLength: 24 }); console.log(arr1.resizable); console.log(arr2.resizable); 

Output:

false true

Example 2: This example resizes the ArrayBuffer only if it is resizable.

function changeSize(arr, size) {  if (arr.resizable) {  arr.resize(size);  return "Resized";  }  return "Maximum capacity reached"; } let arr1 = new ArrayBuffer(8); let arr2 = new ArrayBuffer(8, { maxByteLength: 24 }); console.log(changeSize(arr1, 24)) console.log(changeSize(arr2, 24)) console.log(arr1.byteLength); console.log(arr2.byteLength); 

Output:

Maximum capacity reached Resized 8 24
