javascript - How to get current byteoffset from the start of the dataview while advancing the buffer?

Question

I'm trying to get the updated byte offset after inserting an element to dataview.

However, I don't know how to calculate the updated byte position from the beginning of the array.

My code:

let buffer = new ArrayBuffer(6);
let dataView = new DataView(buffer);
let bufferCounter = 0;
dataview.setUint16(0, 17);
bufferCounter += dataview.offset; // Is this the correct way?
console.log(bufferCounter); // Expecting "2", getting "0"

How can I get the result I was expecting?

Thanks.
