What Hacker News says?
I think the sentiment of "you dont know what you dont know" is especially cumbersome with JS, since its usability is so much defined by its extensions (WebAPIs, runtimes etc.) Reading into specs (ECMAScript[0], W3C[1]), some more approachable explanations[2] of them and some implementations[3, 4] of embedded engines seem to be my approach.

HN discussionI have to mention Dmitry Soshnikov's "JavaScript. The Core" webpage. The concepts explained in version one published in 2010 helped me land several contracts. Now I see he has "JavaScript. The Core: 2nd Edition". Thank you Dmitry! http://dmitrysoshnikov.com/ecmascript/javascript-the-core-2n...

HN discussionDude, just admit you’re wrong about what kinds of patterns are natural or common in JS and about what was “in mind” when it was created. Here are some popular big JavaScript toolkits/frameworks: Closure Library, YUI, Dojo, Prototype, MooTools, ExtJS, Base2, JavaScriptMVC, Backbone. http://closure-library.googlecode.com/svn/docs/closure_goog_... http://yuilibrary.com/yui/docs/api/classes/Base.html http://livedocs.doj…

HN discussionWhen I started out, this and "Secrets of the JavaScript Ninja" didn't help me understand. For me, after months of trying to understand JavaScript, Dmitry Soshnikov's post, JavaScript. The Core, made understanding closure, prototype, and scope chain crystal clear in about 30 minutes.

HN discussion@ameyv, thanks for the feedback! Yes, there will be more courses related to implementation of programming languages: Automata Theory, Theory of Parsing, Essentials of Interpretation, and others. There are some lab sessions for the Garbage Collectors class, e.g. Writing a Memory Allocator from Lecture 6, where we implement an allocator similar to `malloc` function: http://dmitrysoshnikov.com/compilers/writing-a-memor…

HN discussion"W3schools obviously fills a niche that the W3C isn't filling" This alone is the biggest problem - that you think they are somehow related. They are not. "W3Schools has gone through the work of reading the spec and turning it into a good reference" No. You're wrong. THIS: http://dmitrysoshnikov.com/ecmascript/ ...is a good reference based on a spec.

HN discussionWhen I was learning more about this, I found this[1] article to be of great help. I think the key idea is that JS is a prototype-based OO model. It's easy to forget because there are so many abstractions[2] that act like a JS is a static class based OO language. [1] http://dmitrysoshnikov.com/ecmascript/chapter-7-1-oop-genera...

HN discussionFor highly technical analysis of the ECMA Script (JavaScript) language I highly recommend the series of articles of Dimitry Soshnikov. http://dmitrysoshnikov.com/ecmascript/javascript-the-core/ These series of articles are probably the deepest series into the language on the Internet (surpassing even Crocford's articles as far as depth goes).

HN discussion[SPOILERS] I got tripped up by question #5 of one of the expert quizzes [1] due to a difference between ActionScript 3 and JavaScript [2]. In AS3, `(a).b` is equivalent to JS's `(null, a).b`. That is, the `this` binding is lost in AS3 (but not JS). I thus thought the anser was "20, 10, 10, 10", and not "20, 20, 10, 10". AS3 is not a superset of ES3 as most people believe. [1] http://dmitrysoshnikov.com/ecmascript/th…

HN discussionI like the courses offered by Dmitry Soshnikov [0][1]. I have gone through Parsing algorithms and Garbage Collection algorithms courses, they were really fun. I messaged him on twitter recently and he was kind enough to offer nice discount for Cyber Monday [2] [0] - https://news.ycombinator.com/user?id=DmitrySoshnikov [1] - https://www.udemy.com/user/dmitry-soshnikov/ [2] - http://dmitrysoshnikov.com/
