Next, for printing date and time we need moment module, let's install it. npm install moment --save.   After successful installation of `moment` a node module package will be created inside folder and also package.json file. Now here comes the actual part, create a folder names 'nodejs' and move nodemodules, package.json (package-lock.json also , if present) inside nodejs folder. After moving the folder structure should be as below. ...
