Lets start...

• get started with npm install eslint --save-dev && eslint --init

4 ways to define linting

• package.json

{
    "name": "mypackage",
    "version": "0.0.1",
    "eslintConfig": {
        "env": {
            "browser": true,
            "node": true
        }
    }
}

• .eslintrc

{
  ...
}

• command line --- globals: var1: true var2: false
• on the top of each file with comments /*eslint-env node, mocha */

eslint 2.x vs 1.x

You can nest .eslintrc files

check sample fragment

• if you use webpack, add eslint-loader in your wepack.dev.js as a preloader (preloader so that your colleage doesnt makes mistake to put babel-loader before the eslint-loader)

others bla bla
