##NOTE Currently the npm and bower packages are commited to source control but I plan to make a branch available that does not contain these packages.

##Overview This repository contains the examples for my book "Learning Underscore.js".

The folders and examples are named in such a way they can be explored outside of the book context.

If these examples prove useful to the community I intend to create a branch after the book is finished (or even a separate fork) and accept further additions or even significant changes unrelated to the content of the book.

##Examples index The examples are organised in these sections (that match a specific chapter of the book):

Getting started (Chapter 1: Getting started with Underscore.js)

  2. Starter example with _.find() - code, preview
  3. Starter example with _.countBy() - code, preview
  4. Examples for and _.reduce() - code, preview
  5. Examples for and _.reduce() with IIFE (immediately invoked function expression) - code, preview
  6. Revealing module pattern - code, preview
  7. Examples for and _.reduce() with revealing module pattern - code, preview
