The time to scan with ncdu on directory with massive number of directories and files can be long and you don't get progressive stats.

I made jsdu to get progressive (and recursive) size.

I mostly only use jsdu on a few top levels directories, and use ncdu for the rest or after the stats is cached by jsdu.

You can install jsdu with "sudo npm i -g jsdu" or run it without install with "npx jsdu"
