How to install latest node version?

I would like to install latest node

Hi @Piyush_Duggal, welcome! Here’s a doc that shows you how to update the version of Node your project uses: Can I change the version of node.js my project uses? - Glitch Support

You’ll only be able to use the versions already installed on containers - which is as high as Node 16 currently. I don’t yet have a date for when Node 18 will be available.

How about the latest version of npm? I noticed something about a version 9.x

The version of npm available is whatever comes coupled with the version of Node you are using. This table of releases show what comes with what: Previous Releases | Node.js
