Function.prototype.bind replacement that provides an unbounded hidden property on the returned bounded function, that contains the original unbounded function

Install

NPM

  • Install: npm install --save unbounded
  • Module: require('unbounded')

Browserify

  • Install: npm install --save unbounded
  • Module: require('unbounded')
  • CDN URL: //wzrd.in/bundle/unbounded@1.1.0

Ender

Editions

This package is published with the following editions:

  • unbounded aliases unbounded/index.js which uses Editions to automatically select the correct edition for the consumers environment
  • unbounded/source/index.js is Source + ESNext + Require
  • unbounded/es2015/index.js is Babel Compiled + ES2015 + Require

Older environments may need Babel's Polyfill or something similar.

Usage

This package functions like Function.prototype.bind, however it exposes a hidden unbounded property on the returned bounded function that contains the original unbounded function.

This is very useful as it means you can do (fn.unbounded || fn).length to always get the correct amount of arguments, or (fn.unbounded || fn).toString() to always get the source code of any function instead of getting function () { [native code] } for bounded functions.

You can use unbounded via require('unbounded').binder like so:

const {binder} = require('unbounded')
const context = { hello: 'world' }
function a () {
    return this.hello
}
const b = binder.call(a, context)
equal(b(), context.hello, 'context was correct')
equal(b.unbounded, a, 'unbounded was correct')

Or you can patch Function.prototype.bind directly:

require('unbounded').patch()
const context = { hello: 'world' }
function a () {
    return this.hello
}
const b = a.bind(context)
equal(b(), context.hello, 'context was correct')
equal(b.unbounded, a, 'unbounded was correct')
