What this snippet does
Recursion handles unknown depth naturally — the base case (non-array) pushes the value, the recursive case digs deeper.
Expected output
[ 1, 2, 3, 4, 5 ] [ 1, 2, 3, 4, 5 ]
Why practise typing this
Typing algorithms 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.
