JavaScript ArrayBuffer maxByteLength Property Last Updated : 18 May, 2023 Comments Improve Suggest changes Like Article Like Report JavaScript maxByteLength in ArrayBuffer is used to set the maximum size of ArrayBuffer in bytes. This specified length is the maximum length to which we can resize the ArrayBuffer. This is a read-only property and can only be set when the ArrayBuffer object is created and cannot be changed afterward. If this property is left blank it is by default set to the byteLength specified during object creation. Syntax: {maxByteLength: val} // To set max value arr.maxByteLength // To get max value Parameter: It has one parameter only Return Value: When used as a getter it returns the maximum value in Number. Example 1: This example will set the maximum value and print it on the console. JavaScript let arr = new ArrayBuffer(8, { maxByteLength: 24 }); console.log(arr.maxByteLength); arr.resize(28); Output: When we try to resize the array beyond it's maximum capacity it will throw an error. Example 2: This example will try to increase the byteLength beyond it's capacity.
