Course Intro and Overview
4 Lectures 12:09

JavaScript AllStars is a curated course featuring JavaScript's legendary inventors, developers and evangelists.

It consists of a variety of lectures, lessons and tutorials from elite JavaScript programmers and community leaders.

Designed to provide high level insight and information, JavaScript AllStars is intended for experienced JavaScript coders - and those who plan to be!


After a brief beta release, JavaScript AllStars will be reset as a paid course (sign up while it's free!).

As a "curated" course - made up of content and lesson sifted from public sources - it naturally invites a pretty good question: "Why should we pay for something we can get for free?"

This brief video introduces the nature of curation, why it provides value (or doesn't, depending on your view) and how it helps you structure your learning.

Thanks. Looking forward to seeing you in JavaScript AllStars.

On Curation

Perhaps only a geek can appreciate a 12 minute interview on the origins of a programming language.


But this one is very interesting as the man who jump started the entire JavaScript project - virtually inventing the language - sat down to talk a little shop, a little history and a little trash about the early days of our beloved JavaScript.

Eich is a highly engaging, very smart guy who's got a terrific story to tell. And he tells it brilliantly. Enjoy.

Brendan Eich on the Foundations and Purposes of JavaScript

This course contains the following lectures, lessons and exercises: 1. Introduction - Intro videos - Interview: Brendan Eich (JavaScript Inventor) 2. JavaScript AllStar: Doug Crockford - AllStar Profile - Advanced JavaScript (1 hr 6 minute lecture w/time stamp outline) - JavaScript "The Good Parts"…
