No. It means that when you invoke `console.log` in a browser it "logs" a reference to an object instead of serialising it.

This log is still synchronous, but when you expand it in the console its properties are dereferenced and may be different from when the original log was made. The log, however, is still instantaneous and synchronous.

OK, agreed. That's an important distinction. The console log will synchronously receive a reference to an object; later if you expand something in the log window it shows you the current state.

I would say the argument is lazy evaluated.

Thanks! I figured it meant that, but nice to see it without having to mess around.
