Just an IO with map and chain

IO.js

import compose  from 'ramda/src/compose'
import curry    from 'ramda/src/curry'
import map      from 'ramda/src/map'
import always   from 'ramda/src/always'

const chain = curry((fn, m) => m.chain(fn))

function IO(run) {
  const map   = fn => IO(compose(fn, run))
  const chain = fn => IO(() => map(fn).run().run())

  return { run, map, chain }
}

const valIO = x => IO(() => x)
const logIO = x => IO(() => compose(always(x), console.log.bind(console, 'from logIO'))(x))

const flow = compose(chain(logIO), map(x => x + 5), chain(logIO), valIO)

console.log(flow(3).run())
