JavaScript Bound invocation


Example

The bind method of every function allows you to create new version of that function with the context strictly bound to a specific object. It is specially useful to force a function to be called as a method of an object.

var obj = { foo: 'bar' };

function foo() {
    return this.foo;
}

fooObj = foo.bind(obj);

fooObj();

This will log:

bar
