Benchmark: _.flow vs flew - MeasureThat.net

Script Preparation code:

const flow = (funcs) => {
  const length = funcs ? funcs.length : 0
  let index = length
  while (index--) {
    if (typeof funcs[index] != 'function') {
      throw new TypeError('Expected a function')
    }
  }
  return function (...args) {
    let index = 0
    let result = length ? funcs[index].apply(this, args) : args[0]
    while (++index < length) {
      result = funcs[index].call(this, result)
    }
    return result
  }
}

const flew = (funcs) => {
  if(funcs.some(func => typeof func != 'function')) {
    throw new TypeError('Expected a function')
  }
  return (...args) => funcs.reduce((arg, fn, i) => i == 0 ? fn(...arg) : fn(arg), args)
}

const add = (i, j) => i + j
const mult = (_, i, j) => _ * i 
const funcs = [add, mult.bind(this, 3)]

function doFlow() {
	return flow(funcs)(1,2)
}
function doFlew() {
	return flew(funcs)(1,2)
}
