For those wondering, you can get around this globally by listening during the capture phase and stopping propagation. document.addEventListener('DOMSubtreeModified', function( e ) { e.stopPropagation(); }, true );

As a consumer, I would love this. But my understanding is that most/many companies have found "retargeting" to be very effective. So it's annoying, but we also seem to respond to it. As long as that second part remains t

Just to expand on that a bit for anyone who might not know this: var s = new String('foo'); typeof s; // 'object' That is, when you use the `new` keyword, you get back an object instead of a primit

Right, but you wouldn't curry those functions.

by kevincennis 11y ago
It's all relative, right? If I'm writing some super perf-sensitive code like manipulating an array of PCM data for Web Audio stuff or doing a complex canvas animation, then the savings of not using Function#bind are probably kind
109.
by kevincennis 11y ago
You can get a lot of value out of `Function#bind()`, which has been around since ES5. That doesn't let you curry functions, but it does give you partial application, which I think is actually more useful on a day-to-day basis. If you&#

Hey. Thanks so much for the feedback. It's been a while since the first time I ever tried to do this, so it's a bit difficult to remember exactly what my initial approach was. But I definitely remember the moment where I realized

Both good questions. The immediately invoked function is really just a slightly less verbose way to do this: function resolver() { } return resolver(); The reason that I gave it a name instead of using an anonymous functi

OP here. That was kind of my intent (learning exercise rather than super practical real-world technique) -- but I'll admit I probably could have picked a better title.

Yeah, sorry about that. I realized afterwards that a better title would probably have been "Writing a Curry Function in JavaScript".

Hey. Author here. Thanks for the feedback. I completely agree that culture fit and giving candidates a chance to learn about the company/position are hugely important to any interview. I could write entire posts about each of those. I

In ES5+, the global `undefined` is immutable, so it should be pretty safe unless someone declared a local `undefined` var in an outer scope.

by kevincennis 11y ago
I agree that default parameters will be a much nicer solution to this problem, but using the OR operator is a very common practice in JS, and any dev with more than about 5 weeks experience will recognize and understand that pattern pretty

I'm a little unclear on this stuff: connection.call('collection', 'users'); Is `connection` a function? As in, you're essentially using Function#call and passing the string 'collection' as `thi

In my experience, it's way easier to write client apps against a REST API. If you look at frameworks like Backbone, you can basically create models/collections for a simple CRUD app just by adding some values to a declarative hash

Maybe I missed it, but is there an estimate for when we'd see the first Node release that has io.js changes merged in? I know there's been a "convergence" repo for a while now, but I couldn't quickly get a sense of
