NPM is a package manager for nodejs and many other languages. Currently I was running nodejs version v0.10.37 on my system. I was in required to install Latest nodejs package on my system. After searching I found the best and easier way to update your nodejs version using NPM quickly. It works perfectly for me and hope so for you.
Steps to Upgrade NodeJs:
Use the following steps to install or upgrade nodejs to latest available version.
