@ed,
Setting the prototype in the constructor is not a good idea, as you are redefining the class methods on every construction. I don’t think I ever said that. So the second form is the approriate form.
very nice, enjoyed this a lot and it’s really refreshing to see a talk that gets down to interesting differences and pieces of the language, instead of just covering syntax.
I know you are a big eclipse fan for java dev, are you using mostly browser windows for js dev or another setup?
Nice video as usal!
May i point out that actionscript works almost the same about closures, apply() and call()
__proto__ & prototype existed with as2 but are not available anymore (thank god btw)
Just mind-blowing presentation. You ran through the idiosyncrasies in the language. Writing the language in the functional way feels more natural, you have dealt OO developer perspective of approaching the language which is very appropriate as they are lot of OO folks jumping in to the language with OO approach in mind. Explanation on differences between js and browser heaps were thought provoking.
Reference section citing some of the recent developments makes the presentation more complete.
Curious to know if you have read the book pro javascript design patterns by justina diaz and ross harmes.

[...] Misko Havery JavaScript presentation. [...]
i think you glanced over the topic but didn’t go into it. but can you explain what are the side effects of declaring
Something = function() {
this.someProperty = ‘test’
Something.prototype.someFunction = function() {
//do something
}
}
vs.
Something = function() {
this.someProperty = ‘test’
}
Something.prototype.someFunction = function() {
//do something
}
