Well, by doing a brief search on the internet, including SOen, there is no stated advantage. Until then, let and const offer some 'protection by following rules' more than var , but they do the same job.

To say no advantage, some browsers still do not accept the declaration of let and const , but otherwise, var can already be retired.
