PSST! I've Got a Presentation Next Week – JavaScript Library Comparisons

I am cranking through some code examples and plenty of research for this thing. It should kick incredible amounts of JavaScript ass. Come to think of it, it's a ninety minute presentation, so it better kick ass :) I'm going to look at load times, execution times, ySlow scores, codebase and add pure editorial commentary for several popular libraries (at minimum, jQuery, YUI, Prototype, and Dojo), as well as pure JavaScript and my own bare-bones library.

If you're a Boston JavaScript nerd, I hope to see you there.

Here's the description:

Our next JavaScript Meetup will be held on Thursday, April 30th at Microsoft Research Center located at One Memorial Drive in Cambridge. You should come to the 11th floor to be let in. There is also parking available at a cheap evening rate in the building.

Rob Larsen , Principal Presentation Engineer at Cramer, will demonstrate comparisons between raw JavaScript and utilizing the more popular JavaScript libraries currently available.

After the presentation | demonstration, we will go around the room introducing ourselves and asking the group for advice | opinions on any JavaScript-related issues members are facing.

Microsoft will provide pizza again. What a nice company!

Please RSVP and bring guests. We always have lots of pizza left over.

JSON Feeds For Fun and Profit Part 3- wherein Eval() kind of bums me out

(and several months later I finish my little JSON series…)

So far my exploration of JSON has been a fun-filled walk in the park. Moonbeams and rainbows. All that.

This last post on the subject is slightly less cool as I get into one of the least attractive components of the whole JSON thing- the use of eval() to transform a text response into a proper JavaScript object. The use of eval() is one of the reasons I originally was a little shy about using JSON. Why? eval() is slow and I try to stay away from slow if at all possible. That and the idea of eval()-ing code from some third party makes me wary.
