pipeFunctions

Performs left-to-right function composition.

Use Array.prototype.reduce() with the spread operator (...) to perform left-to-right function composition. The first (leftmost) function can accept one or more arguments; the remaining functions must be unary.

typescript

const pipeFunctions = (...fns) =>
  fns.reduce(
    (f, g) =>
      (...args) =>
        g(f(...args))
  );

typescript

const add5 = (x) => x + 5;
const multiply = (x, y) => x * y;
const multiplyAndAdd5 = pipeFunctions(multiply, add5);
multiplyAndAdd5(5, 2); // 15
