One line of command to get node.js version upgrade

Node has a module called n (the name can be short enough...), which is specially used to manage the version of node.js.

First install the n module:

?

1	npm install -g n

Step 2:

Upgrade node.js to the latest stable version

?

1

n stable

Is not it simple? !

The version number can also be followed by n, for example:

?

1	n v0.10.26

or

?

1

n 0.10.26

It's that simple, how can this be done? ? ! !

In addition, share a few common commands of npm
