ActionScript vs. JavaScript vs. Objective-C vs. Scheme Comparison Chart

The ActionScript® scripting language lets you add complex interactivity, playback control, and data display to your application. You can add ActionScript in the authoring environment by using the Actions panel, Script window, or an external editor. ActionScript follows its own rules of syntax, and reserved keywords, and lets you use variables to store and retrieve information. ActionScript includes a large library of built‑in classes that let you create objects to perform many useful tasks. You do not have to understand every ActionScript element to begin scripting. If you have a clear goal, you can start building scripts with simple actions. ActionScript and JavaScript are both rooted in the ECMA-262 standard, the international standard for the ECMAScript scripting language. For this reason, developers who are familiar with JavaScript can find ActionScript immediately familiar. Animate includes more than one version of ActionScript to meet the needs of different kinds of developers.

Objective-C is the primary programming language you use when writing software for OS X and iOS. It’s a superset of the C programming language and provides object-oriented capabilities and a dynamic runtime. Objective-C inherits the syntax, primitive types, and flow control statements of C and adds syntax for defining classes and methods. It also adds language-level support for object graph management and object literals while providing dynamic typing and binding, deferring many responsibilities until runtime. When building apps for OS X or iOS, you’ll spend most of your time working with objects. Those objects are instances of Objective-C classes, some of which are provided for you by Cocoa or Cocoa Touch and some of which you’ll write yourself.
