Pipeline Processor Using Reduce

.js

function add(i) {
  return i + 1;
}

function mul(i) {
  return i * 2;
}

function sqr(i) {
  return i * i;
}

const pipe = (val) => (stages) => stages.reduce((input, stage) => stage(input), val)

let stages = [add, mul, sqr]
let result = pipe(1)(stages)
console.log(result) // 16
