Just like V8, the Dart VM doesn't have an interpreter. The code is directly compiled to (fairly crude) machine code. Later, the hot parts are replaced with better machine code.

That shouldn't stop anyone. Dart works fine in every modern browser (and IE9), because you can compile it to JavaScript. Generating minified Dart code is one line and compiling to minified JS is also just one line. If you do one in your bui

Bitbucket works fine for this. Its wikis are just markdown/git. You can add stuff offline or you can use the web interface.

> giving people shortcuts I don't see any problem there. The code is very compact. There are lambda expressions, method cascades, and user defined operators. Also, structure is baked in. You don't need any of that AMD boilerplate code.

RSS just isn't very popular. Firefox also removed that RSS icon from the address bar a few months ago. Do you think Mozilla did that because they "oppose the open web"? No, of course they don't. They got rid of it because virtually no one u

Even IE9 is pretty old. It's over 2 years old by now. IE8 is over 4 years old. IE11 will be released soon. How many versions of IE do you intend to support?

Why not? Placebos also look like the real thing, don't they? Anyhow, in cases like this it's always nice to save all the data you can get. The correlation you'd like to demonstrate might not exist at all. However, if there are many paramete

It could, for example, be used to demonstrate that people are more willing to reveal some private information if you make them jump through a few hoops to gain this "privilege".

Yes, the SIMD optimizations aren't quite there yet. You can already write SIMD code though.

"Minority browser"? What's that supposed to mean? Anything other than Chrome? Or, if we go back a few years, anything other than IE? In case you didn't know, there are 3 very important browsers: Chrome, Firefox, and IE. Right now, Firefox g

We had lossy RGBA many years ago with JNG (a simple PNG/JPG mashup format), but Mozilla killed the format along with MNG. The reason was that the MNG lib added about 100kB to the installer. They suggested to use Flash instead. (Yes, serious

You could write the back-end in Dart, too. The Dart VM can do IO out-of-the-box. Just like the Node executable, it can be used to run command line scripts, web servers, or anything else you can think of. Anyhow, since the front-end only com

"JS is the crappy ill-suited compiler target everyone is forced to use." Now, if you say instead that it's low-level ("assembly"), fans of JS feel smug about using it instead of being offended. However, at the same time you hint that JS is

Dart's biggest selling point is that it's very nice to use and that it's free of nasty surprises. Have you ever written a somewhat bigger JavaScript application with a few thousands lines of code spread across dozens of files? It's horrible

"Run". Yes, just ~600 times slower. At that speed it probably won't be very useful. You have ~50 msec for an operation which is perceived as instantaneous. If it takes 30 seconds (600 times as long), people will not use it. It simply isn't

You were able to do the same without asm.js. Problem is, it's way too large and way too slow. People aren't doing these things because they simply aren't feasible. If you could compile Python directly into that asm.js subset of JavaScript,
