View source for Getting nodejs v12

* <code>sudo apt -y install curl dirmngr apt-transport-https lsb-release ca-certificates</code>
* <code>curl -sL <nowiki>https://deb.nodesource.com/setup_12.x</nowiki> {{!}} sudo -E bash -</code>
Installing the NodeSource Node.js repo finishes with:

 
## Run `sudo apt-get install -y nodejs` to install Node.js 12.x and npm
 ## You may also need development tools to build native addons:
      sudo apt-get install gcc g++ make
 ## To install the Yarn package manager, run:
      curl -sL https://dl.yarnpkg.com/debian/pubkey.gpg {{!}} gpg --dearmor {{!}} sudo tee /usr/share/keyrings/yarnkey.gpg &gt;/dev/null
      echo "deb [signed-by=/usr/share/keyrings/yarnkey.gpg] https://dl.yarnpkg.com/debian stable main" {{!}} sudo tee 
 /etc/apt/sources.list.d/yarn.list
      sudo apt-get update && sudo apt-get install yarn
Installing nodejs now automatically installs npm.

(Debian gets v7.5.2, Ubuntu gets v6.14.15)

attempting to install npm (on Debian)now causes:

 Some packages could not be installed. This may mean that you have
 requested an impossible situation or if you are using the unstable
 distribution that some required packages have not yet been created
 or been moved out of Incoming.
 The following information may help to resolve the situation:
 
 The following packages have unmet dependencies:
  libnode72 : Conflicts: nodejs-legacy
  nodejs : Conflicts: npm

(Let's see what happens if I don't try to fix this...)

installing build-essential installs gcc g++ & make for you... & does a better job of it...

The Yarn package manager is a new thing. hhhmmm... No clue what it's actually for.
