- curl -sL https://rpm.nodesource.com/setup_10.x | sudo bash -
- sudo yum install nodejs

 UPDATE

How to update Node.js to latest version

1. Uninstall Node.js. Click the Start menu, type "Change or Remove a Program", click on the item shown, find Node.js in the list and uninstall it.
2. Delete directories, both C:\Program Files (x86)\nodejs\ and C:\Program Files\nodejs\ if they exist.
3. Install the latest, https://nodejs.org/en/download

The uninstall/delete/install seems unnecessary, but it often is and this will save your time. These instructions come from Microsoft.
