Iâ€™m also guessing itâ€™s _not_ â€œDominican Summer League, a branch of affiliated minor league baseball played in the Dominican Republicâ€ or â€œDesign Science License, a copyleft licence for intellectual propertyâ€. The suggestion Iâ€™m getting at here is to please donâ€™t assume your readers are familiar with every CS-ish acronym floating around out there. wow powerleveling lord of the rings power leveling maple story power leveling wow power leveling

Great ideas! I love making JS more natural and this concept really refactors the implementation details away. Good call on the circular reference, BTW.

Great code, thanks for publishing the presentation.
It would be cool if there would be a DSL for client side forms which would talke care of presentation, validation and extra features. Is there some of this in the making?

Not a fan of the last example. How about:

trade(”state”).to(”Canada”).when(”us-state”).is(”Ohio”);

DSL in the context of this presentation means domain-specific language. Sorry the presentation isn’t more explicit. I prefer the leave my slides as high-level as possible and let the accompanying talk flesh out the details. Since few were able to actually hear the talk, I’ll be going into more depth in the tutorial.

VS –

Whoa! Good catch… I’ll need to adjust that vocabulary.

Beware of is identifier usage -- is will be a reserved keyword in near future (http://www.mozilla.org/js/language/es4/core/lexer.html). VS

I feel like an idiot for having to ask this, but what is “DSL”?

Wikipedia’s disambiguation page suggests that maybe it means “Domain-specific programming language, a programming language designed to be useful for a specific set of tasks” or possibly “Data Serialization Language, a way to describe data independent of a programmable language”. I’m guessing it’s the first of those.

I’m also guessing it’s _not_ “Dominican Summer League, a branch of affiliated minor league baseball played in the Dominican Republic” or “Design Science License, a copyleft licence for intellectual property”.

The suggestion I’m getting at here is to please don’t assume your readers are familiar with every CS-ish acronym floating around out there.

(Nice: my captcha challenge question for this comment is “What three letter acronym is what we use to style web pages?”)

I’m really glad you found the slides useful on their own. I was a little worried they would provide little benefit without the accompanying talk, so I’ll be expanding the talk into a multi-part tutorial on my blog very soon (as in, I think I’m posting part 1 this afternoon). Thanks for the link!
