What this snippet does
DFS goes as deep as possible before backtracking — naturally implemented with recursion using the call stack.
Expected output
[ 'A', 'B', 'D', 'E', 'C', 'F' ]
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.
