Different versions of Node

You should install nvm to manage different versions of Node.

Stable versions are even (0.10, 0.12), unstable versions are odd (0.11) numbers.

Then you can install and use 0.12 by doing:

nvm install 0.12
nvm use 0.12

Libraries to Install

-g flag stands for global installs.

npm install -g babel

npm install -g mocha

You should run npm install in the root folder to install dependencies defined in package.json file.

To install npm modules and save them to package.json, you have to use --save flag

npm i underscore --save

To run tests:

mocha test/sql.js

mocha test/test.js

To run ES6 features, you need at least Node version 0.11 installed.

As Node version 0.12 is out, it is better to use that.

node --harmony test/es6/yield.js
