Haxe Complete Course / Control Flow

throw

Learn throw in Haxe through the exact construct, a dedicated example, a boundary case, and a mastery check.

10 min read • Beginner

throw is an atomic Haxe lesson inside Control Flow. The example uses the specific syntax, command, API, instruction, or language rule named by this lesson.

Study the construct itself, then change one relevant input and predict the result before running it. That keeps this lesson focused on throw rather than on generic Haxe syntax.

Topic-specific example

haxe-02-10.hx

haxe Try It Live

class Main { static function main(){ throw new haxe.Exception("invalid state"); } }

Edge case / engineering note

Compile throw for at least one target and watch for target-specific behavior where the feature crosses a platform boundary.
