for each loop

Learn for each loop in ActionScript 3 with a construct-specific explanation, a unique example, a practical boundary, and a mastery check.

10 min read • Beginner

for each loop is an atomic ActionScript 3 topic inside Loops & Functions. The example below uses the actual construct named by the lesson rather than a generic placeholder.

Focus on what for each loop 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-02-02-for-each-loop.as
actionscript Try It Live 
for each (var n:int in [2,4,6]) { trace(n*n); }
Edge case / engineering note

Change the key input in this ActionScript 3 example and predict the result first; the named construct should be the reason the behavior changes.
