Javascript Library

Hello,

I would like to use a javascript library to simplify my coding
process.
I know a few: JQuery, Dojo, Yahoo UI, ...

Which one do you advice me to use?

Thanks,
Miguel

This question comes up frequently on comp.lang.javas cript. There is
currently a thread that shows the feeling of many of the regulars here
that none of these libraries will do...

Richard, do you still assert that no one is saying "write it all
yourself"?

I don't see Richard in this thread. Regardless, your library does not
have to be 100% self-written. IIRC, Richard stated something to that
effect in the other "please recommend a library" thread.

There are pros and cons to each, but I recommend jQuery. It is
powerful, compact, easy to understand, and has an active support
community.

The first two are right out. Why take the time to learn an API that

Powerful perhaps, but the copy I have here is 82K. Perhaps it would
lose 30K or so minified.

Having recently looked over the code, I can tell you it is poorly
written and full of mistakes. Any time saved coding will come back to
you in maintenance and trouble-shooting.

Learning the API takes, perhaps, a few hours. Even if it does have
terrible code behind it (it does not), the improvement in end result
will still be beneficial to most, because most are already writing
terrible code that doesn't even have the benefit of working most of
the time.

There is a minified download option. Check it out.

Without any examples or real critiques to back up that broad
statement, it's worthless.

I've been writing javascript for over 10 years, and I've seen poorly
written code. jQuery is not poorly written. Nor is it "full of
mistakes".

I can see things in the code that I would change and improve, and a
number of them are actually already in as tickets for changes in
future versions. No free collaborative effort is without its problems.

Would you also throw out the Wikipedia as "junk" because you find an
article with technical errors?
Any time saved coding will come back to
you in maintenance and trouble-shooting.
My real-world experience differs from your hypothesis. I can measure
the _huge_ benefits of using jQuery in real dollars, and it is
significant.

I'd love to hear about your experience with jQuery and the maintenance
and trouble-shooting that you were required to do.

Run it through JSLint. Then search it for "userAgent. " Then look at
the logic that tests for a function. That's three strikes right
there.

Isn't that what I said? Running it through a minifier will lose about
30K. I just tried it here and my estimation was almost exactly right.

Try searching this very newsgroup for jQuery. You will find lots of

Which is about as useful as validating HTML. Great for academic
purposes, perhaps it will catch a few errors, etc.
But in the end it doesn't matter if code passes analytics, just if it
accomplishes the goal or not. My goal never includes "pass
validation". Validation is merely a tool to reach my goal, when
needed.
Then search it for "userAgent. "
Browser sniffing is not encouraged, and in some cases in jQuery it is
really unnecessary. There are cases where it is beneficial.
Rather than writing lengthy logic to solve for every possible case,
you can write shorter logic to solve for a subset of cases you care
about.
It's not ideal, but it is a strategy. The amount of browser sniffing
in jQuery is minimal.
Then look at the logic that tests for a function.
It may not be perfect, but have you ever come across a real-world case
where it has failed for you?

Me neither.

jQuery's code is not terrible. It is a substantial improvement over
most javascript code written by average developers. In my experience.
There is a minified download option. Check it out.
Isn't that what I said? Running it through a minifier will lose about
30K. I just tried it here and my estimation was almost exactly right.
The packed version is 26kb. Plenty small.

Try searching this very newsgroup for jQuery. You will find lots of
examples.
But why should I look up past examples? You said you recently looked
over the code and found that it was poorly written and full of
mistakes.
Surely you could provide some examples from your recent investigation?
I've been writing javascript for over 10 years, and I've seen poorly
Lots of people can make that claim. How many of them are competent to

I'm not sure "lots of people can make that claim". I consider myself
to be very knowledgeable about Javascript development, and I disagree
with your conclusions. Surely not everyone who disagrees with you is
categorically an amateur?
written code. jQuery is not poorly written. Nor is it "full of
mistakes".
Then despite your vast experience with JavaScript, you still don't get
it.
What don't I get? You are not providing any actual arguments. You
might as well just say "You're stupid!" and stick your tongue out.

Further, have you considered that perhaps it is you who just doesn't
get it?
Would you also throw out the Wikipedia as "junk" because you find an
article with technical errors?
That is an odd comparison.
Perhaps. The point is, just because you notice a few flaws in
something does not mean it is worthless. It merely means it has flaws.
Which means it was probably developed by humans. If your goal is
perfection, you'll never find it.
My real-world experience differs from your hypothesis. I can measure
the _huge_ benefits of using jQuery in real dollars, and it is
significant.
And how would you quantify the benefits of "using jQuery" in dollars?
#1:
(Previous time to develop functionality) - (current time to develop
similar functionality) = Time Savings
Time Savings * Pay Rate = Money Saved

#2:
(Number of JS bugs before) - (Number of JS bugs now) = Bug Savings
(Bug Savings) * (Avg Time to Fix JS Bugs) * Pay Rate = Money Saved

Consider the effects of introducing jquery to a large development
team:
1) Reduced time implementing similar functionality as before
2) Reduced number of bugs
3) Improvement of UI because developers have access to pre-made
plugins
4) Less time needed to write functionality from scratch and research
browser quirks
5) No problem reports from any end users

Now, how are you arguing that using jquery is not a huge benefit?

You would recommend that we stop using it and start coding from
scratch?
I'd love to hear about your experience with jQuery and the maintenance
Having read the script, I concluded it was worthless. Therefore, I do
not use it.
Then how would you know anything about an increase in maintenance
caused by using jQuery?
Can you quote the experience of anyone else who has used it and found
it to be a maintenance problem?
Or hell, can you quote anyone who has used it and found it to be a bad
decision for any reason?
Do you have any real-world experience with it?
If not, how do you possibly feel justified in criticizing it?
