Call function constructors with an array of arguments that spread
npm install newifyCalling 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
``js`
function Student(firstName, lastName, birthYear){
this.firstName = firstName
this.lastName = lastName
this.birthYear = birthYear
}
We want to easily call the function constructor like
`js
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!
`js`
var arr = ['john','scot', 1980]
var s = require('newify')(Student, arr)
`
npm install newify
As in the above example, just give newify a function and an array of args
`js`
var arr = ['john','scot', 1980]
var s = require('newify')(Student, arr)
`
