JS has saved me many hours of mind-numbing, error-prone manual keyboard work by giving me a way to hack together a simple bit of automation as a web page.
Even when a computer has been ham-fistedly locked-down by an overzealous IT department, I can almost always still access a text editor and a browser that will load local HTML files.



“rd” and “rmdir” only work on empty directories in MS-DOS (and I assume, by extension, in Windows shell). “deltree” is for nuking a complete tree including files, as the name suggests.
