Array methods

Learn Array methods in ActionScript 3 with a construct-specific explanation, a unique example, a practical boundary, and a mastery check.

10 min read • Intermediate

Array methods is an atomic ActionScript 3 topic inside Collections & XML. The example below uses the actual construct named by the lesson rather than a generic placeholder.

Focus on what Array methods changes: the input, binding, control path, object state, collection, runtime effect, or language contract. Then alter one value and verify that the behavior changes for a reason specific to this feature.

Topic-specific example

actionscript-04-02-array-methods.as
actionscript Try It Live
var a:Array=[1,2,3]; trace(a.map(function(n:int,...rest):int{return n*2;}));
Edge case / engineering note

Check the input collection shape, whether the operation mutates or returns a new value, and what happens for an empty collection.
