"Are all those new fancy DOM traversal, XPath and XSLT APIs really not faster than parsing and joining of strings?" It cannot be understated how much slower touching the DOM is compared to doing string manipulation. Any DOM touching - but

Only quiet because we're working so hard. We're releasing the alpha on October 16th (at the jQuery conference in Boston) so we're a bit frantic at the moment. Either way we're hoping to get a blog post up this week.

The jQuery project has been working on this this particular plugin for a while now. Based upon what Yehuda wrote up in his original Handlebars.js blog post: http://yehudakatz.com/2010/09/09/announcing-handlebars-js/ He also recommends the

We opted not to use this particular technique for two reasons: 1) It's not nearly as versatile. You can use the if statements on elements, attributes, text - anything you wish - there is no restriction on its contents or location. 2) In ord

This was originally posted to the jQuery forum: http://forum.jquery.com/topic/jquery-regular-expression-revi... The changes have already been made: http://github.com/jquery/jquery/commit/9dc6e0c572b9c809a3a4c...

Yep - they're going to be 100% Themeroller-able. It's going to be a bunch of work on our end but the ability to have a unified, good-looking, UI that works across all platforms is just too enticing to ignore.

jQTouch has been out for a couple years at this point - a two month "chill" period before release seems totally appropriate. Honestly, I don't see the "chill" as being a bad thing in this regard: jQTouch and Sencha Touch are doing mobile we

Yep - that's correct. Since jQuery is a completely community-driven project and funded entirely by donations we wanted to open up right away to bring more people in. While we're rather confident in the direction that we're heading - doing i

To preempt a few questions that are bound to pop up: What about jQTouch? While jQTouch is a great framework and we're proud to have it as part of the jQuery community - we really wanted a mobile framework to exist that would truly support a

I've read your comment a couple times now but I'm struggling to think of an example that hasn't improved with the new layout. Not only does the new layout include a much more in-depth listing of properties and methods but it also has a much

It's been over a year since Jack posted to the ExtJS forums: http://www.sencha.com/forum/member.php?2-jack.slocum Probably safe to say that he's no longer involved.

It's a concern of ours (the jQuery Project) as well. We've been actively working on mobile over the last couple months (mostly getting jQuery core in a better state with regards to supporting more mobile platforms). We see one major gap in

Good question - I was inspired heavily by Dean Edwards' original Base Class library, it seemed to make the most sense when I was using it. The original code: http://dean.edwards.name/weblog/2006/03/base/ The current code: http://code.goo

Huh, weird. This seems to crib very heavily from my original Simple JavaScript Inheritance implementation: http://ejohn.org/blog/simple-javascript-inheritance/ It even uses the 'classy' name and logo (stemming from an April Fools joke tha

This was demoed at today's jQuery Conference: There is no canvas used to render the tiles (it's all images). There is some canvas used to compute out the hit detection logic - but I suspect that that's something that could be generated serv

"This has nothing to do with 'existence' of [] (I'm not even sure what existence could mean here)." Ah sorry, I was referring to the fact that the array was already created and within another object that we were referencing. But yeah, thank

by jeresig 17y ago
To start, you need to know that JavaScript has type coercion. Numbers can become strings, strings can become numbers, and arrays can become strings. Thus, for example: [] in a string context becomes "". "" in a number context becomes 0. Thu

The critical phrase is: "According to the numbers presented by the Taskspeed benchmark..." Is jQuery, as a whole, 2x faster in 1.4.2 compared to 1.4.1? Provably not - we didn't make changes to all of jQuery (and even if we did, how would we

"The project just makes breaking changes way too often, e.g., the earlier 1.4 builds try to take over IE's event model and get it wrong, not only breaking jQuery's own code but also breaking all the tried and tested workarounds we've been u

Other way around - be sure to double-check the raw data at the bottom (3.6 is considerably faster than 3.5).

by jeresig 17y ago
Erm - how would it slow down people's code? We're already doing a check to see if a tag name is being used and optimize based upon that, we just added one additional check to optimize for body. There is absolutely no way in which the check:

If your question is "How many times in January is [there going to be a code release of] jQuery" then the answer is only twice: jQuery 1.4 and 1.4.1. However we've also released the 14 Days of jQuery (jquery14.com), jQuery.org, the new jQuer

No worries - I definitely appreciate feedback. Glad you're enjoying jQuery :)

by jeresig 17y ago
I should clarify: We do get a ton of feedback during the alpha/release candidate phases - it's just that there always seems to be a few things that end up slipping through in the end, one way or the other, hence the soon-after .1 release.

by jeresig 17y ago
I'm always surprised how phenomenally hard it is to get people to test alphas and release candidates - it isn't until the actual major release hits the floor that a ton of input starts to roll in. Every release I think it'll be different bu

In some way the browsers already have made the decision. The new JSON.parse method available in Firefox, Safari, and IE 8 is capable of parsing a valid JSON string and turning it into a JavaScript object. The exception is the one provided b
