Create object from class name in JavasScript ECMAScript 6

Question

I want create object factory using ES6 but old-style syntax doesn\'t work with new.

I have next code:

export class Column {}
export class Sequence {}         


        

Answer 1

For those of you that are not using ES6 and want to know how you can create classes by using a string here is what I have done to get this to work.

"use strict";

class Person {
    constructor(x, y) {
        this.x = x;
        this.y = y;
    }
}
window.classes = {};
window.classes.Person = Person;

document.body.innerText = JSON.stringify(new window.classes["Person"](1, 2));

As you can see the easiest way to do this is to add the class to an object.
