Man do not waste your time to learn JQuery.
Learn JavaScript, which is what JQuery is after all, but just bundled into bunch of classes that are supposed to make life easier, but in fact they add a layer of complexity which is just a time waster :(
Stick with JavaScript. You will know JS for real, your code will be smaller and faster.
In fact the sooner that JQuery dies, the better for the World :)

Wow. For once ThinkDeep is actually correct and has all of his fact straight. Never thought I would ever give him a thumbs up, but I did.

ThinkDeep, I really appreciate that thoughtful answer.
Although, I think the counter argument is that there are lots of JS Libraries in JQ that makes the job of coding front end much cleaner and faster. But your points are well taken and the more I research think valid given HTML5 and JS really render JQ moot. But still if I could learn JQ fast, would like to do so, since many companies list that in their Job Req. Thanks.

Learning jQueery so that it can show on your resume is a very valid reason for learning it. However, I am not sure I would want to work for a company requiring such a bloated mess. Such a company is constraining their IT personnel to fit a paradigm that in the long run does not work well at all. If they are doing that to their IT people, I would assume that they have other short-sighted paradigms that may bankrupt them. So, a job requiring jQueery MAY be a short term position there.

I have enrolled on quite a few programming course on Udemy. https://www.udemy.com/

They change their prices regularly so just wait until everything becomes $10, which is their current "special" price.

Hi GurdMuller.

Apart from their stupid prices changes, they have some really good courses for a broad range of subjects.

I am not affiliated to them in any way. Just a happy customer.

Hope that helps )

I discovered Coursera a while back. You can take all kinds of classes (and tons of computer related ones), for free, and they are very good. Universities from all over the world participate in hosting these classes. Most of them take 68 weeks to complete, and you do it at your own pace and time. Here's the link: https://www.coursera.org/

Hi, this is exactly what I have been looking for, for online self-learning.
Have you taken courses here?
If yes, which course(s) did you take? And how did you like it?
Also, I am not clear about whether these courses are Free or you have to pay for them! Do you know?
Thanks.

Hi,

I have taken one complete course from Tel Aviv University, and thoroughly enjoyed it. It was called Understanding Plants. A great asset, very interesting. I've started a couple others, and couldn't finish them because we were in process of moving and I didn't have time. I'm taking another one right now, about beginner's html coding, from Michigan State University. It looks like it's going to be good, too.

You can take them for free, or pay and get college credit for them. I do free!

So one can take all the courses for Free? And choose to only pay, if one ones to get Credit for these course? And as Free student do we get all the same services and products as paid Students?

Yes, you are correct. You can take any course you want for free. The only thing you don't get with the free one is the college credit diploma. Everything else is the same. There are hundreds, maybe thousands of classes offered, and the hosting universities are all over the world. It's really fun! Of course some of the professors are more enjoyable than others, just like any in classroom. The one I had in Tel Aviv was really fun, and he's the leading person, in his field, in the world.

Hum! Very interesting. I shall give them a try by taking one of the courses that I have been looking to take. Such as Object oriented Php. Hopefully it will be a good investment of time and not a waste of time, which is the worst thing. We shall see. But from what you are saying it should be a good investment of time.

Actually a question, which is not clear from their Site.

Can one take the courses any time that one wants to? That is learn by watching Videos online and follow course material online and not stick to any schedule?

Or do we have to take each course at a designated starting time and follow an online class at a designated schedule?

Thanks.

You can work on the course at any time during the duration of the class dates listed. It seems there may be a little leeway at the end of the schedule, but I don't know how much or if it's always available. I often miss working on the class for a day or so, and then I get back at it and do however much I can, any time of day or night! That's the beauty of it! But I need to be done on or about the ending date.

Ok, that does not quite answer my question. But I guess the only way about is just to take a class and see. Although, I hate to waste time.

Y2G, even if you get only HALFWAY through ANY learning course, you have not wasted your time. Every time you enter the class you learn something.

The only way you could waste your time is if you failed to learn anything as you studied.

Well, that is True. But an even a bigger Truth is that it is best to finis the course and get a degree, which requires one taking classes at only reputable and real orgs.

I see you are already quite familiar with JavaScript. JQuery intrinsically is nothing much more than a new JavaScript dialect.

I use it only when I cannot use JavaScript, and usually go to http://www.w3schools.com to see which options are available. Since they list both JS and JQuery solutions, I can make an informed choice.

You may get bored sitting through a JQuery course, as quite a bit of it is probably just about pretty much the same as JavaScript.

BTW, I concur about JQuery being useful for certain things. Some of what is in JQuery is simply not available in standard JavaScript. That makes these extensions valuable. I usually decide on a case by case basis.

I know you want to learn jQuery, but I fail to see why you would want to spin your wheels learning something as bloated as jQuery. The time spent learning it is probably better spent learning javascript as MOST of the time you can do the same thing faster, with less code, and with fewer debugging headaches. Not only that, but your site will load faster, run faster, and have fewer problems that you need to keep fixing. Wasting the user's bandwidth is the same as stealing from him since it is costing him money that he should not have to pay. Wasting your time constantly fixing the fixes that you have fixed umpteen million times before is costing you time and money.

Most of the sites that I see using jQuery tend to be bloated messes filled with errors, and often will not even display pages properly on any but the coders' computer. For example, I visited one site today using jQuery (a government site) and the pages won't even load because they are stuck in an endless jQuery loop.

For longest time I resisted using JQuery because of exactly what you referred to, that is the "Bloat" issue. And instead I have always insisted in using pure JavaScript. Ya, I am pretty much a pro in JavaScript. However, unfortunately certain things can only be done in JQuery, such as uploading an image via AJAX to a Php program on the server. How would you do this in pure JavaScript? I dont think it can be done with pure JavaScript and JQ is only way to do such things.

Gurd. You are right but must also be wrong :)
To be exact you are right because I searched (on Google, Anoox, etc.) for:
"Image upload via AJAX and Php without JQuery and in pure Javascript"
and cannot find any really good solution to this!
In fact best thing I found is this:
http://blog.garstasio.com/you-dont-need-jquery/ajax/

I cannot make sense of it. If you can WOW!
With that said, you are wrong since JQ after all is written in JavaScript. So whatever you want to do that requires

JQuery should be doable, for sure, via pure Javascript, since JQuery is just a bunch Javascript functions. Right?

Now I know that lots of new Developers coming out of Tech academies are Hot on JQ. But they are Hot about any new fangled tech jargon, without realizing that JQuery is just a bunch Javascript functions. not?

TG, although I am in full agreement with you that all Web page development should be done in JavaScript and not JQ, the fact remains that as per example I gave sometimes, the solution seems to be only available in JQ.

If you MUST use JQ, and I don't see why you would need to, just copy and paste ONLY the code needed to do your job. Downloading 384K of useless code, especially on a slow computer, is downright frustrating.

Yes, but the problem is that the JQuery source code is the most frustrating bunch of code to read through! I mean it is like encrypted Code the way it is written. So you will have to spend long time to do what you said.

Yeh, I know. Just saying that that is what SHOULD be done to keep page sizes to a manageable minimum. It irritates me to no end when I see 384k of jQuery on a page only 10k long, especially when a tiny part of jQuery is only used one time.

Yes, that is true. And indeed so amazing that more of the Web and Internet World does not have a problem with JQ huge download size. And now we have a whole eco system developed and developing around JQ, so it is bound to get worse.
