Javascript why Product2 is never called contrary to Product1

Question

I'm experimenting with javascript function as object and async. Why Product2 below is never called ?

function Product(title) {
  this.title = title;
  this.getInfo = function() {
    return this.title;
  }
  return this;
}

async function Product2(title) {
  this.title = title;
  this.getInfo = function() {
    return this.title;
  }
  console.log(this.title)
  return this;
}

async function main() {
  console.log("start")


  var product = new Product("car");
  console.log(product.getInfo());

  var product2 = await new Product2("car 2");
  console.log(product2.getInfo());

  console.log("end")
}

main();

Answer 1

async function Product2(title)

As this is async, There should be an uncaught TypeError when you are doing this:

var product2 = await new Product2("car 2");

cause Product2 is not a constructor anymore.

A function marked with async will return a promise.

A constructor on the other hand returns the object it is constructing. Thus we have a situation where you want to both return an object and a promise: an impossible situation.

Answer 2

new Product2 will create an instance of an object of product2

You cannot use await and new keyword together.

After being suggested https://github.com/cyrus01337/invites, I took a look and found a more elegant solution using async def on_invite_update(member, invite):

Thank you Lukasz in the comments for the suggestion.
