bind-this

Function scope binding with partial application.

Usage

Require the module. Available on npm as bind-this.

var bind = require('bind-this');

Binding

In most cases you will want to pass this and a function, this will return a new function bound to the current context.

this.foo = 'bar';

var bound = bind(this, function () {
	return this.foo;
});

// Try and 'override' the context
bound.call({}); // 'bar'

Note that the global scope will be used by default unless otherwise specified.

Pass a string instead of of a function to resolve the function from the context.

var parseRadixTen = bind(this, 'parseInt', null, 10);

### Partial Application

Any further arguments will be used to partially apply the function. Pass null to 'skip' a parameter. Any skipped parameters will be filled from left to right using the values passed to the bound function when executed.

var append = function (str, append) {
	return str + append;
};

var appendBar = bind(append, null, 'bar');

appendBar('foo'); // 'foobar'
