Cross-Platflorm node.js directory node module, which includes mkdir and mkdirSync utilities which behave like the UNIX command "mkdir -p" which can be given a path with lots of non-existent nested directories and create any that are missing. One thing missing here that could be added in the future is the optional 'mode' argument, which exists in…
