In TypeScript the following is also valid:

class Something{

    value: Number

class SomethingElse{

    value: Number

    foo: String

    bar: SomeOtherThing[]

function AddSomething(v: Something)

{

    v.value += 1;

var ex = new SomethingElse{

    value: 3,

    foo: “TypeScript is fake types”,

    bar: []

AddSomething(ex);

Why does it work? Because in TypeScript as long as you have a “shape” that fits, it’s the “same type.”

Complete and utter insanity to me, to pretend there’s any real type checking, when types are entirely fake and made up.

Ive spent years in construction and built out quite large projects.

What’s the best way to contact you?
