Learning Javascript vs. jQuery

I got the Wrox.Beginning.JavaScript.3rd.Edition and wanted to start learning it from scratch, then my boss came along and said that why bother, learn jQuery. Can I understand jQuery and work with it although I am a newbie and have limited knowledge in ASP.net, vb.net, some C#, and basic HTML?!

So what's your question? JQuery is a framework built on the top of a language JavaScript. To use JQuery confidently, you should get familiar with JavaScript. JQuery contains a bunch of useful patterns and utils that mask the incompatibilities of the browsers. Using a JavaScript framework make sense as it allows you to focus on your problem instead of the problem of the JavaScript implementations of the browsers.

For further details on JavaScript frameworks, see SO question »Which Javascript framework (jQuery vs Dojo vs … )?«. For learning JavaScript, learn the good parts.

Libraries will alwas contain nonessential complexity, but they can save some headaches if they're not too bloated or already present on the end users' systems. Best use would be to learn javascript while using jquery, and then slowly remove the crutch of using jquery. While it's powerful, it does add significant overhead, nonessential complexity, and potential opportunities for abuse, just like flash. There are no silver bullets.

I would say the statement is akin to you reading a C#/VB.Net book and having your boss say "Don't bother, just learn ASP.Net". You really don't get much from the latter without the former.

If you already have an understanding of C#, you'll have a head start learning Javascript and it shouldn't be too hard to pick up. I'd stick with that Javascript book though, since you need to know Javascript to use jQuery. Once you are comfortable with Javascript, move on to learning jQuery. The jQuery docs are VERY helpful and can answer almost any question you have.

Good luck with learning it, it'll be worth it.

Maybe your boss is trying to save you some time learning the basics of Javascript and start you off learning jQuery right away but I think this would be a bad idea.

Understanding the basics of javascript is key to using jQuery successfully. jQuery provides shortcuts and solutions to problems (cross browser problems etc) but it is not a language unto it's self.

My advice, learn javascript, learn about handling events in different browsers, inserting in to the DOM and then start using jQuery. You will appreciate it a lot more and be a better coder for it.

if all your manager is asking from you is to show and hide some elements, or fade in and out a couple of images, or request some data via ajax and display it then learning jquery and its api is perhaps all that you need.

but if you (or your manager) are concerned about performance, maintainability, code reuse and generally understanding what the *ell is going on 'back there' then learning the language itself is a safe bet.

I would suggest grabbing a copy of JavaScript: The Definitive Guide, which will give you a general understanding of what it is and how to use it, and much more. While you are at it, I also suggest John Resig's Pro Javascript techniques. This guy really knows his javascript inside-out (works for mozilla, author of jQuery, amongst others).

As for jQuery, you don't really need to buy a book. Just browse through the API and have a look at its source code. Perhaps you won't understand much, but there are some cool stuff going on that will make you think.

jQuery is made from javascript. :)

It would be a very good idea to read the source-code of jQuery to enhance your overall understanding of javascript...

Definitely learn both at the same time :)
Good luck and have fun.

jQuery removes the need for many bad Javascript habits. However, you will frequently need to know more than just jQuery to get non-trivial work done.

You'll need to learn both, but try to pick up habits based on jQuery.

JQuery provides a good layer of abstraction for interacting with DOM elements. You can do a lot of interesting things with it quickly and easily. But there are probably many things that JQuery won't do for you. You'll need to use regular JavaScript for that.

It is entirely possible to learn jQuery without learning every bit of javascript first. However, to be productive and and extend the functionality of plugins etc you will need to know javascript.

I would suggest that you do a bit of both. Continue learning Javascript but when you want to implement functionality make use of the jQuery library.

jQuery is javascript. I think you're on the right path. Learn javascript well and you'll be able to make better use of jQuery.
