Utilizing TypeScript: Implementing a class within an object with explicit typing

I'm struggling with explicitly assigning a type in TypeScript from a class nested within an object (essentially a namespace):

let obj = {
    hello: class {
        constructor: function () {
            console.log('hi');
        }
    }
}

// Implicit type assignment in global space works
var inst = new obj.hello();

// However, explicitly assigning the type doesn't work.
var inst2: obj.hello;
function assign() {
    inst2 = new obj.hello();
}

Click here to view on TS Playground. The output seems correct, but I'm confused as to why the typing information for inst2 defaults to any.

Appreciate any insights!

Answer №1

The inst variable does not have the type hello. Instead, it belongs to an unidentified class type, as indicated by the hovering cursor over inst in your example. Being undisclosed, you are unable to directly reference it in the code.
