Can you create nested classes in TypeScript?

Question

Is there a way to nest classes in TypeScript. E.g. I'd like to use them like:

var foo = new Foo();
var bar = new Foo.Bar();

Answer 1

In modern TypeScript we have class expressions which you can use to create a nested class. For example you can do the following :

class Foo {
    static Bar = class {
        
    }
}

// works!
var foo = new Foo();
var bar = new Foo.Bar();
