Typescript private class inside class or something similar

Question

I'd like to declare a private class, only to be used inside the file it was defined, is this possible? For example declared inside another class:

export class MyParentClass {     class MyChildClass {     } } 

or inside the same file:

export class MyPublicClass {    //Usage of MyPrivateClass  }  class MyPrivateClass { } 

Answer 1

module MyModule {     export class MyPublicClass {         private myPrivateClass: PrivateClass;         constructor() {             this.myPrivateClass = new PrivateClass;         }         public test() {             this.myPrivateClass.test();         }     }      class PrivateClass {         public test() {             console.log('it works');         }     } }
