What this snippet does
Strategy replaces conditionals — instead of if-else on algorithm type, you swap in a different function at runtime.
Expected output
[ 1, 1, 3, 4, 5, 9 ] [ 9, 5, 4, 3, 1, 1 ]
Why practise typing this
Typing design patterns 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.
