Did You Know?

There's more to Flash than the timeline. As the program has evolved, more sophisticated types of interactivity have been added to it, all controlled by its built-in programming language, called ActionScript.

ActionScript in Flash 5 is different from previous versions. It has become very flexible and powerful, capable of performing complex calculations and comparisons. Its syntax and vocabulary are very close to that of JavaScript, so if you're familiar with that language or anything similar, you won't be disconcerted. In fact, you can take many JavaScript routines and use them in ActionScript with little or no modification.

Note

ActionScript conforms closely to the same ECMA-262 specification as JavaScript (see http://www.ecma.ch/ for more information on the standard). It deviates from the specifications in some respects (capitalization rules for variables, for instance) to provide backward compatibility with previous versions of Flash.
