As someone who will be working extensively with JavaScript and JQuery, I hear the community is strong so I figured I would ask what a beginner should been keen in understanding when developing mobile applications. Like any other language, I wish someone would have walked in the first day of class when programming with C and said to me, "if you don't learn everything about malloc() and free() today, you will fail!" Or when I was writing with Java and heard that private and static are essential for every function and variable too late. See what I mean about learning the most important so I don't get frustrated with the details later.
My current attempt at figuring this question out is reading a book, but like most books, they don't expect you to ask what is the high-level re-occurring concepts. I have used CSS and HTML and have not used scripts or Jquery as much when developing websites.

Read "JavaScript the Good Parts" by Douglas Crockford http://www.amazon.com/JavaScript-Good-Parts-Douglas-Crockford/dp/0596517742/ref=sr_1_1?ie=UTF8&qid=1419857713&sr=8-1&keywords=javascript+the+good+parts
This will give you what you need for JavaScript. I don't know "the best" source for jQuery, but start here: http://learn.jquery.com/

If your new to Javascript Syntax I would highly encourage you to check out the Code Academy's Javascript Track here.
If your new to programming in General I'd also encourage you to learn about functional programming which is very important in Javascript (Very useful especially when you start working with asyncrhonous code). A great resource for this is Eloquent Javascript. The book is posted 100% free on the authors website here. I'd encourage you to read chapters 1-5.

I'm a novice in programming. I know a little about programming. Previously I have worked on some projects for my College with Java, PHP and C++. I'm not good at any of those.
I have a tremendous enthusiasm for the web. Also in AI and web-based Mobile application. I have practiced a little of HTML/CSS, JS, PHP, CMS's with no discipline.
Please help me out where I can start, step by step process to mastering my dream.
Thanks in advance.
I shall look forward to hearing from you.
learn JavaScript core consecpt W3school JavaScript
Angularjs from Angularjs
Nodejs from tutorialspoint -nodejs
try to create small web app
It depends upon your choice of action, you would basically have two options UI/UX and Core language developer. As i am a full stack developer working in Mobile, i will explain how i started.
UI/UX
Start practicing with HTML5 and CSS3 since its most advanced and accepted.
I would prefer:
https://www.w3schools.com/html
Next Learn CSS3 and Bootstrap
Bootstrap website itself provides a good documentation for it.
https://getbootstrap.com/docs/3.3/getting-started
Next Task for you would be Javascript which is everything if you ask me.
https://www.w3schools.com/js/
You can Learn Angularjs if you want, as its really important. but i would ask you to leap to Angular2 and Typescript which follows the OOPS concept.
Youtube also provides great tutorials especially thenewboston channel
Since you have interest in AI, start with some python, then move on to R Programming.
I hope this would help you.

I am working on an update of a curriculum for teaching non technical students the basics of programming, esp. programming for the web.
I prefer coffeescript over javascript for the (most times) much shorter and - as I think - better readable code.
On the other hand there are thousands of examples written in Javascript which are harder to understand if you know only about Coffeescript.
For the last years I just told my students to use a split screen in the editor, code CS in one frame and see JS in the other to see what is the translation of the CS statements in JS. And I showed the how to use CS2JS and JS2CS converter. The idea behind this is to make things visible like what "for-each" or "for-in" statements of CS do, as they are shown in JS in an unfolded way.
(I know this example leaks a little bit as ECMA 5 is rolled out now for a little time, but I am doing this for didactic reasons for a little while now)
Another problem is that there a not so much code hinter etc. for CS then for JS available.
EDIT
As the community seams to see this question to be opinion based, I precise it:
What toolchain do you use to make an easy entrypoint available for newbees to learn CS?
My pipeline builds on brackets.io as a webservice, node, gerrit, gitlab, ungit, jenkins, jade, less, coffeescript, ...
I have the need to make everything available totally offline so I wrap the tools in docker containers and VMs.
Before this question is closed as opinion-based, which indeed it is, let me comment that I cannot imagine the value in teaching non-technical students about CS vs. JS transpilation issues. They must have MUCH better things to spend their time on. As lovely as CS is, it is a dialect. Teaching it is like teaching Cockney slang in an English class. Furthermore, notwithstanding all the great code written in CS and the great benefits in efficiency it brought to those who used it, for better or for worse it is now on its way out, superseded by ES6 and TypeScript and eventually ES7.

I am trying to learn Javascript.There are some excellent books and great authors that became standard in JS world - As I can see, they all have their own way of interpretation of language. It can be sometimes confusing for the novice in Javascript.I wonder, how usefull can be to learn directly from ECMAScript language specification as it was published by the authors of the language ?
It's probably much better to learn from the tutorials, as the specification is designed for people implementing JavaScript parsers/interpreters, not for people learning JavaScript itself.
If you want to learn from a reference, the MDN is a fantastic resource. There are also plenty of tutorials out there.
The specification is optimized for defining the language from the point of view of its implementors. It is not optimized for teaching it to someone that is new to the language.
A good learning reference has also many things that are not covered in the language spec, like common APIs (like the DOM and a JS framework) and common patterns (ex.: the module pattern, namespaces, etc...). While it is true that some people might have some coding practices you don't agree with you should not immetiately dismiss what they say, unless you really want to learn everything and fall into every trap yourself. As long as you have a mental framework of what you consider to be the best practices in general you should be able to identify what you agree with or not.
JavaScript is one of the most controversial languages in existence, there is no clear author and no clear documentation.
The best project I know of is Mozilla Developer Network (or MDN), it's pretty extensive and comprehensive.

this site has been a great help to me. I am working as a UI designer, and i am very interested in learning Javascript, but i am not able to find a right way to start from. I don't have a programming background.
I need a book for Javascript, which is totally for a Noobs, starting from the fundamentals. I tried reading Douglas Crockford's Javascript the good parts, but i wasn't able to understand much.
Please suggest me some books
Try out this new site:
http://www.codecademy.com
It really will help you get a hang of javascript. It's an interactive way for learning javascript.
If you're looking for a book, I'd recommend O'Reilly's Head First JavaScript. You can get it from their site or cheaper from Amazon.
I started recently using eloquent javascript and it is indeed a good book. Along with that Mozilla Documentation helped. But the best way to understand the language is to use it and see it in action. Ask a friend of yours to introduce you to firebug and how firebug is used to alongside with Javascript debugging. That will help you to get a grasp of how javascript is used to real world. Once you know that you will find that Javascript as a language is really simple, it's applications (and concepts such as AJAX) and it's libraries (jquery) are the ones that are making it really really powerful
Make sure you read Pro JavaScript Techniques. It is concise with a wealth of information.
Then there's the JavaScript: The Definitive Guide. Also make sure you get Secrets of the JavaScript Ninja when it gets published.

This is a question for general discussion. Are there any good, comprehensive resources for useful JavaScript design patterns. I am trying to avoid references that attempt to coerce JavaScript into, say, Java by imposing patterns more suited to another language. Let's let JS be JS and shape our patterns around the strengths.
Please any discussion would be valued by more than just me, I suspect.
Here's an on-line resource:
Essential JavaScript Design Patterns For Beginners
Here's a good one:
This is an awesome book by O'Reilly. It builds on their "JavaScript: The Good Parts".
It references a lot of the patterns mentioned in the "Gang of Four" book and notes a lot of the problems solved in that book are trivial to solve with JavaScript.
APress has a book called "Pro Javascript Design Patterns" that is probably just what you're looking for. While the author (Diaz Harmes) is certainly not "the gang of four", I think he does a pretty good job; I know I learned quite a bit from it (and it got 4.5 stars on Amazon).
Amazon link: http://www.amazon.com/JavaScript-Design-Patterns-Recipes-Problem-Solution/dp/159059908X
I'm not sure why no one has listed this, but Addy Osmani's JavaScript design pattern book is fantastic and freely available online. He really digs deep to show you the nuts and bolts of each pattern.
http://addyosmani.com/resources/essentialjsdesignpatterns/book/
This is one of the best design patterns resources I've found for JavaScript
http://shichuan.github.com/javascript-patterns/
It's aimed for JavaScript as we know and not necessarily trying only use concepts of other languages.
Peter Michaux has some decent articles
Also see Crockford's articles (and his book)
A new book on the subject by Stoyan Stefanov: Object-Oriented JavaScript: Create scalable, reusable high-quality JavaScript applications and libraries
