Bound-native-methods NPM

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:

Object

Native Form	Bound Form
Object.getPrototypeOf()	::getPrototype()
Object.setPrototypeOf()	::setPrototype()

Symbol

Native Form	Bound Form
Symbol.for()	::toSymbol() 1
Symbol.keyFor()	::key()

Number

Native Form	Bound Form
Number.parseFloat()	::toFloat() 1
Number.parseInt()	::toInt() 1

Math

Native Form	Bound Form
Math.pow() 2	×
Math.random()	×

Date

Native Form	Bound Form
Date.UTC()	×
Date.now()	×
Date.parse()	::toUnixOffset() 1

Array

Native Form	Bound Form
Array.from()	×
Array.of()	×

ArrayBuffer

JSON

Native Form	Bound Form
JSON.parse()	::toObject() 1
JSON.stringify()	::toJSON() 1

Notes:
Bound methods whose names start with "to..." are to be applied to strings (with the exception of ::toJSON() which can be applied to a variety of data types)
Please use the exponentiation operator ** instead
