bind-plus

A utility which provides apply-like semantics for Function.bind

Description

JavaScript functions can be called through the native methods call and apply taking an argument list and an array of arguments respectively.

Function.bind follows the same semantics as Function.call, taking an argument list and allowing us to create 'bound' functions which can be called at a later time.

bind-plus allows you to create the same bound functions but from an array of arguments (like Function.apply) rather than an argument list (like Function.call).

Installation

Install using npm

npm install bind-plus --save

And require in your project

var bind = requrie('bind-plus');

Usage

API

bind(function, [context], args);
  • function - the function to create a bound version of.
  • context - (optional) the this value of the function.
  • args - An array or array-like object of arguments.

Examples

The following examples, albeit contrived, show how you can create bound functions.

With no context

functions which do not rely on this do not need a context.

function foo (a, b, c) {
    return a + b + c;
}
 
var bound = bind(foo, [1, 2, 3]);
 
bound(); // 6

With context

functions which do rely on this will require a context.

var foo = [1, 2, 3],
    bound = bind(foo.join, foo, [' and ']);
 
bound(); // "1 and 2 and 3"
