What this snippet does
Because generators implement the iterator protocol, they work anywhere an iterable is expected — spread, for...of, destructuring.
Expected output
[ 1, 2, 3, 4, 5 ] [ 0, 2, 4, 6, 8, 10 ] 1 2 3
Why practise typing this
Typing generators 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.
