Huge diiference between size calculated by size-of and size shown in devTools

[mahsashadi]

I print win object size in console by your size-of module, and also attach it to window, to show it in chrome devTools.

console.log('mywin size is:',  sizeof(win));  //shows 22M
window.mywin= win;                            //shows 20B

The question is that is this difference reasonable? which one is really consumed by memory?
