How can you map the differences between Javascript objects?

Is actionscript better than javascript and What is the differences between javascript and Actionscript?

• Answer:

  When you can choose between them, Javascript is better simply because it is an open standard supported by all browsers, while Actionscript is proprietary (owned by Adobe) and needs a browser plugin to run. Actionscript is unavoidable when working with Flash. Actually, to make this judgment based on Javascript being open source is too simplistic. Javascript is a prototyped language, and therefore is not truly object-oriented, which can make it slow and difficult to develop large applications in. Actionscript 3.0 is object-oriented and therefore can support complex design patterns and more robust applications. In addition, Javascript is rendered differently depending on the browser supporting it. Therefore, performance of Javascript applications varies widely. Because AS3 runs in the Flash player its performance is consistent across many devices.
