The arrayBuffer.byteLength is a property in JavaScript which gives the length of an arrayBuffer in bytes.
Syntax:
ArrayBuffer.byteLength

Return Value: It returns the length of an arrayBuffer in bytes.

If length of arrayBuffer is given in fraction, it returns length in whole number and when length is given in the form of string then it returns length of zero (0).
