Keeping class secrets hidden?

This thought just crossed my mind, and I'm looking for a way to make classes private in TypeScript. Let me explain the situation:

Inside my directory Typescript/circle/circle.ts, I have the following code snippet:

class Circle {
  PI:number = 3.14;
  radius:number = 0;
  constructor(public radiusInput:number){
    this.radius = radiusInput  
  }
  getArea(){
    return this.PI*(this.radius*this.radius);
  }
  getCircumfrance(){
    return this.PI*2*this.radius;
  }
}
 var fourCircle:Circle = new Circle(5);

Now, when I navigate to another folder, Typescript/enums/enums.ts, I am able to create an instance of the Circle class. However, I do not want that capability. Is there a way to effectively make the Circle class private in TypeScript? Any insights on achieving this?

Organize your classes and other data types within modules in TypeScript to maintain a structured approach. By encapsulating them in modules, you can easily reference them from external files by using the export keyword with the class definition. The concept of module in TypeScript is reminiscent of the namespace feature in C#.

module MyTypes {
class Circle {
  PI:number = 3.14;
  radius:number = 0;
  constructor(public radiusInput:number){
    this.radius = radiusInput  
  }
  getArea(){
    return this.PI*(this.radius*this.radius);
  }
  getCircumfrance(){
    return this.PI*2*this.radius;
  }
}
}
