[node.js] How do I update Node.js?

Some Linux distributions such as Arch Linux have Node.js in their package repositories. On such systems it is better to use a standard package update procedure, such as pacman -Suy or analogous apt-get or yum commands.

As of now (Nov 2016) EPEL7 offers a pretty recent version of Node.js (6.9.1 which is an up-to-date LTS version offered on the Node.js home page). So on CentOS 7 and derivatives you can just add EPEL repository by yum install epel-release and yum install nodejs.

CentOS 6/EPEL6 has 0.10.x which isn't supported upstream since Oct 2016.
