Function overloading is the ability of a programming language to create multiple functions of the same name with different implementations. when an overloaded function is called it will run function a specific implementation of that function appropriate to the context of the call.
Does TypeScript allow overloading?

What is the difference between method overloading and method overriding?
1. What is Overloading and Overriding? When two or more methods in the same class have the same name but different parameters, it’s called Overloading. When the method signature (name and parameters) are the same in the superclass and the child class, it’s called Overriding.

What is function overloading C++?
C++ allows specification of more than one function of the same name in the same scope. These functions are called overloaded functions. Overloaded functions enable you to supply different semantics for a function, depending on the types and number of arguments.
Can constructor be private?
A private constructor in Java is used in restricting object creation. It is a special instance constructor used in static member-only classes. If a constructor is declared as private, then its objects are only accessible from within the declared class. You cannot access its objects from outside the constructor class.
Can constructor be overloaded?
The technique of having two (or more) constructors in a class is known as constructor overloading. A class can have multiple constructors that differ in the number and/or type of their parameters. It’s not, however, possible to have two constructors with the exact same parameters.
