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
Most static methods have been exported as is, but a few have been renamed or excluded to better fit the context:
