As commonly known, any npm module can be installed by running a simple command: npm install <module_name>.

I have installed a few modules that I do not use anymoreany more and I just want to get them off. I have a few questions regarding this:

Do we have any command or process to uninstall a module from the root (something like npm uninstall <module_name>) or will simply removing the module files do?
How does it affect us if we keep the unused modules?
