Hey! I'm available for hire (and I appreciate tips)

It's EASY!

First get some build tools

sudo apt-get update
sudo apt-get install \
  git \
  build-essential \
  wget

Now download and extract the source from nodejs.org (check there for an updated link for the latest version)

wget http://nodejs.org/dist/v0.8.18/node-v0.8.18.tar.gz
tar xvf node-v0.8.18.tar.gz
pushd node-v0.8.18
./configure
make
sudo make install
node --version
node

Feel free to play around...

> 0.1 + 0.7
0.7999999999999999
> process.exit() // or `<ctrl>+d`

All is working as expected. Now install served (analogous to python -m SimpleHTTPServer 3000) for fun.

sudo npm install -g served
served 3000

And visit http://localhost:3000 to see it in action. Then hit <ctrl>+c to kill it.

Where to go next?

JavaScript is NOT a language for beginners... yet it's the most accessible language.

The most important thing I will ever tell you: ALWAYS "use strict";!!! Start every javascript file like the one below:

/*jshint es5:true node:true */
(function () {
  "use strict";

}());

If you npm install -g steve-tools you will get mkjs which is what I use to create new files before I even vim them.

Also, make sure you npm install jshint and install syntastic for vim or sublime-jshint, if you swing that way.

Problems

If you ever have problems with node modules the best thing to do is usually to remove all of the node_modules directories from the project (and any directory above it) and try again.

rm -rf ~/node_modules/
find . -type d -name node_modules -exec rm -rf {} \;

Cleaning up after yourself

If you need to backtrack and start over, here's how you get fresh:

Uninstalling for the system

If you believe that something is severly botched and you want to manually uninstall node try this:

mv ~/.npmrc ~/.nmprc.bak

sudo rm -rf /usr/local/*/node*
sudo rm -rf /usr/local/*/npm*
sudo rm -rf /usr/*/node*
sudo rm -rf /usr/*/npm*

Uninstalling locally

mv ~/.npmrc ~/.nmprc.bak

rm ~/local/*/node* -rf
rm ~/local/*/npm* -rf
rm ~/.node_* -rf
