My weekly steps for updating Node.js and related tools

A. Node.js (via nvm in Windows)

1. Install latest LTS/Current Node version

> nvm list                //To check installed versions
> nvm install 14.14.0     //Replace by the version you want to install
> nvm use 14.14.0
> nvm uninstall 14.13.1   //Clean if you need to

2. General check and safe update npm packages
