Usage

const mux = require('mux-arguments')

function muxDemux (arg1, arg2, arg3) {
  mux(obj => {
    arguments.length === 1 // true
    demux.apply(null, arguments)
  }).apply(null, arguments)

  function demux () {
    mux((arg1, arg2, arg3) => {
      arguments.length === 3 // true
    }).apply(null, arguments)
  }
}

muxDemux('foo', 'bar', 'baz')

API

FAQ?

What is muxing / demuxing?

Multiplexing (or muxing) is bundling several things together into one so it can be transmitted efficiently. Demultiplexing (or demuxing) is unwrapping that bundle into its original state. In this module we're multiplexing function arguments.

Why did you write this module?

When building event emitters it's easier to deal with a single data object than writing code to apply n arguments. This module makes it easy to wrap and unwrap function arguments for easy transmission.
