I have a version of node JS as 8.10.0 on Linux mint. 
But I want to install the latest stable version 10.16.0.
For upgrade node js version I have followed the following steps:
- sudo npm cache clean -f
- sudo npm install -g n
- sudo n stable
- sudo ln -sf /usr/local/n/versions/node/10.16.0/bin/node /usr/bin/node
But it has created a problem, now on command node -v I am getting the previous version as 8.10.0 while on run the command as nodejs -v I am getting the upgraded version as 10.16.0.
One more thing which I have noticed here that on command sudo node -v it is responding version as 10.16.0.
How can I upgrade node js version to 10.16.0 so that when I run the command node -v and get upgraded stable version? 
Why I am getting nodejs -v as a command? 
Why I am getting different versions on nodejs -v and on node -v?
