Bound Native Methods

This library exports a collection of bound native virtual methods - static methods of JavaScript standard built-in objects in their bound form - so that they can be used together with the proposed bind operator.

Install

$ npm install bound-native-methods

Usage

import * from 'bound-native-methods';

// Or, be more specific and cut down the build size: //

import {assign, keys} from 'bound-native-methods/object';
0::isInteger();
// true
[3, 6, 9]::max()::is(9);
// true
{'2015-06-01T15:30:00.000Z': 300}::assign({'2015-07-01T15:30:00.000Z': 42})
                                 ::keys()
                                  .map(x => x::toUnixOffset())
                                 ::toJSON();
// [1433172600000,1435764600000]

API
