How can I update my nodeJS to the latest version?

I have installed nodeJS on Ubuntu with following code

sudo apt-get install nodejs

Since I am a new user for ubuntu I also ran this code too

sudo apt-get install npm

Now when I type

 nodejs --version

If you don’t like curl ... | sudo bash - then you can follow the manual instructions, which tells you how to add the Node.js repository to /etc/apt/sources.list.d/ yourself.

NOTE: If you are using Ubuntu Precise or Debian Wheezy, you might want to read about running Node.js >= 6.x on older distros
