Can't export constant in Typescript

Can someone help me please

I have 2 files main.ts and hi.ts

hi.ts:

export const hello = "dd";

main.ts:

import { hello } from "./hi";
...
class A {
    public sayHello() {
        console.log("hello=" + hello);
    }
    ...
}

I have exception:

Uncaught ReferenceError: hello is not defined(…)

How can I see this const variable from class A? Is it possible?

// hi.ts

export const hello: string = "dd";

You must also specify the type of the const.

My answer refers to TypeScript 2+.

// 1.ts
export const AdminUser = { ... }

// index.ts
import * as users from './docs/users/admin';
var adminUser = users.AdminUser;

The only difference between your code and mine is the * operator in the import statement.
