• Using Composed Javascript UI Controllers With Event Delegation

  Posted on Oct 14, 2010 at 7:25 PM

  Given that you're talking about performance issues, one thing you could do to optimize a bit: var controller = $( this ).data( "controller" ); That line is creating a jQuery object that gets used one time. That's all well and good, but if a... read more »

• Using Named Functions Within Self-Executing Function Blocks In Javascript

  Erm - I didn't actually link in the gist. http://gist.github.com/360138 There we go. Sorry about that.... read more »

• Using Named Functions Within Self-Executing Function Blocks In Javascript

  Posted on Aug 16, 2010 at 9:48 AM

  This approach is pretty great - I'm a fan. I picked it up from this gist from Ben Alman (which itself was forked from a gist from Remy Sharp), which shows some other ways to use this technique (such as waiting before the first execution or using setInterval instead of setTimeout). Als... read more »

  @Ben, I should have watched the video. I was waking up and trying to be quiet or might have otherwise. :D Also, I decided to go reading, and on page 117 of the ECMAScript language spec I dug up (well, page 127 of the PDF but it's numbered 117), it explicitly says that when using the... read more »

• Javascript Function() Constructor Does Not Create A Closure

  Posted on Apr 28, 2010 at 8:57 AM

  Posted a bit prematurely: I realize you're aware that the non-quoted syntax works fine, but guess there's likely a reason for trying to use the new Function syntax that I'm not aware of. :D... read more »

• Javascript Function() Constructor Does Not Create A Closure

  Posted on Apr 28, 2010 at 8:54 AM

  I'm not sure if I've really seen functions created like that. If you tweak the interior to something like: var testScope = function() { console.log( scope ); }; Then it outputs 'function' instead of 'window'. Definitely seems like something about going the new... read more »
