newify

1.1.9 • Public • Published

Purpose

Calling function constructors with an array of arguments is difficult. Until spread params are fully supported in all browsers, newify does the job.

For a given function constructor

function Student(firstName, lastName, birthYear){
    this.firstName = firstName
    this.lastName = lastName
    this.birthYear = birthYear
}

We want to easily call the function constructor like

var arr = ['john','scot', 1980]
var s = new Student(arr) //but this will obviously not work as expected.
 
//we need ES6 spread
var s = new Student(...arr)

But since we can't use spread in ES5 ...

NEWIFY to the rescue!

var arr = ['john','scot', 1980]
var s = require('newify')(Student, arr)

Installation

npm install newify

Usage

As in the above example, just give newify a function and an array of args

var arr = ['john','scot', 1980]
var s = require('newify')(Student, arr)
