 ### Pipe
 
-Use `Array.reduce()` to pass value through functions.
+Use `Array.reduce()` to perform left-to-right function composition. The first (leftmost) function can accept one or more arguments; the remaining functions must be unary. 
 
 ```js
-const pipe = (...funcs) => arg => funcs.reduce((acc, func) => func(acc), arg);
-// pipe(btoa, x => x.toUpperCase())("Test") -> "VGVZDA=="
+const pipe = (...fns) => fns.reduce((f, g) => (...args) => g(f(...args)))
+/*
+const add5 = x => x + 5
+const multiply = (x, y) => x * y 
+
+const multiplyAndAdd5 = pipe(multiply, add5)
+
+multiplyAndAdd5(5, 2) -> 15
