What this snippet does
pipe applies left to right (first function first); compose applies right to left (last function first) — different results for the same functions.
Expected output
pipe: 12 compose: 11
Why practise typing this
Typing functional 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.
