A constructor is a special function of the class that is automatically invoked when we create an instance of the class. We use it to create & initialize the instance of the class. We can also add properties to the class using the constructor parameter properties.
Class in TypeScript is a template for creating objects. The class defines the data (fields or properties) and the operations (methods) that we can perform on that data. We create many objects using a single class. In this tutorial, we will learn how to create a class in typescript. How to add Properties and methods to Class. Create objects from the class etc. Â
Private, Public & Protected are the Access Modifiers that we can use in Typescript to control whether certain methods or properties are visible to code outside the class. In this tutorial, let us learn about the similarities and differences between them.

strictPropertyInitialization (Strict Property Initialization) in Typescript is a compiler flag, which when set to true, forces us to assign an initial value to all class properties. If we fail to do so then the compiler will raise the “Property has no initializer and is not definitely assigned in the constructor.” error. This flag was introduced in Typescript 2.7
TypeScript’s type system is based on Structural typing. In a structurally typed system, a type is considered to be compatible with another type if the type has all the properties and methods of that type. But JavaScript is a duck-typed language. Since Typescript Compiles to JavaScript, you can take the benefit of duck typing also.
