Javascript “Not a Constructor” Exception while creating objects

Question

I am defining an object like this:

function Project(Attributes, ProjectWidth, ProjectHeight)
{
    this.ProjectHeight = ProjectHeight;
    this.ProjectWidth          


        

Answer 1

For me it was the differences between import and require on ES6.

E.g.

// processor.js
class Processor {

}

export default Processor

//index.js
const Processor = require('./processor');
const processor = new Processor() //fails with the error

import Processor from './processor'
const processor = new Processor() // succeeds
