August 14, Tags: performance. With every major browser releasing much faster JavaScript engines there has been a flood of comparison tests pitting the speed of each browser against each other. This data is plenty easy to come by, so why not comparisons of AS3 against JavaScript?
That seems much harder to find. What I found was limited to very old data, the newest of which was posted on oddhammer. Even this data reports scores for Flash 9 versus Firefox 2 since it is from I decided to use their test suite unaltered to get updated numbers. My methodology was simple in that I simply used my 3.
I repeated each test a few times and ended up with very consistent numbers. The winners are clear: Firefox 3. Then come the runners up: IE 8, Chrome 2, and Opera 9.
IE 7 brings up the rear with a dismal performance. If I had a team of 5 developers programming at a scrappy start-up, I'd choose JavaScript in a heartbeat. However, in the girth of a large corporation, or academia, you might be safer relying on Adobe's platform. One is type Safetly. Actionscript requires that you set a type for all objects, and JavaScript doesn't for that matter, in JavaScript, one variable may be one type and then immediately set to another type. Actionscript is object oriented.
Although you can sort of have this in JavaScript, Actionscript allows for object inheritance, etc. Essentially the main difference I find is that ActionScript is more a verbose statically-typed class-based language where as javascript is a prototypal language.
Unfortunately there is no type-inference in ActionScript so using Flex Builder gives a warning every time you leave something untyped which I find unnecessary and overly verbose, not only does it make it more verbose than javascript but I find equivalent code to be more verbose than C.
However the extra verbosity does have yield perf improvements and extra type safety at compile-time. Unfortunately this also adds to build time quite significantly, in Java Script apps of any size I'm used to instant feedback whereas my last ActionScript project had build time exceeding 2 minutes.
The key differences are that ActionScript 3 supports both class-based inheritance and prototypal inheritance, enforces namespace bindings between class names and file names, and does not support some global JavaScript methods such as eval. Fortunately, you can do several things to bridge the gap. If you are using the AS3 namespace, any method override must use the AS3 namespace and the override attribute.
If you are not using the AS3 namespace, you can use the prototype methods and propertyIsEnumerable. If you do not use the AS3 namespace, an instance of a core class inherits the properties and methods defined on the prototype object. If you decide to use the AS3 namespace, an instance of a core class inherits the properties and methods defined in the class definition.

What are the key differences between JavaScript and ActionScript 3? Ask Question. Asked 11 years, 9 months ago.
Active 4 years, 2 months ago. The interfaces were identical and interchangeable. What we found was easily quantifiable differences.
For us this was owed to the community coupled with the extremely dynamic nature of JS. There were tradeoffs we considered, latency was acceptably higher on requests to our Node APIs. No strong types to protect us from ourselves, but we've rarely found that to be an issue.
As such we decided to commit resources to our Node APIs and push it out as the core brain of our new system. We haven't looked back since. It has consistently met our needs, scaling with us, getting better with time as continually pour into and expand our capabilities.
Optimize-js I will not describe this tool a lot here, because it's already good done by author on github. I just want to mention that this tool wrap up all immediately-invoked functions or likely-to-be-invoked functions in parentheses what is do a great optimization a JavaScript file for faster initial execution and parsing based on my experience.
When I was evaluating languages to write this app in, I considered either Python or JavaScript at the time. I find Ruby very pleasant to read and write, and the Ruby community has built out a wide variety of test tools and approaches, helping e deliver better software faster.
Along with Rails, and the Ruby-first Heroku support, this was an easy decision.
