What this snippet does
Any iterable — strings, Sets, Maps, generators — can be destructured using array destructuring syntax.
Expected output
x y z 10 20 [ 'a', 1 ] [ 'b', 2 ]
Why practise typing this
Typing destructuring code builds muscle memory for the symbols and indentation JavaScript uses most, which prose-based typing tests never cover. DevType measures your words per minute and accuracy on this snippet and tracks the individual characters you mistype, so later lessons can target them.
