Crack the Code: Secrets of Mastering TypeScript Interfaces| typescript interface

In TypeScript, an interface is a way to define the structure of an object. It describes the properties and their types that an object must have. Interfaces provide a contract for objects to adhere to, ensuring that they have the required properties and methods.

Here's an example of how to define and use an interface in TypeScript:

we will create a typescript file called as example.ts

we will write a greet function to takes an argument of type Person and logs a greeting message to the console, referencing the name and age properties of the provided object.
we will see one example of how to use an interface in TypeScript.

before that we will Install TypeScript: Ensure that TypeScript is installed globally on your machine. You can install it by running
npm install -g typescript in your terminal.

Let's create an interface called Shape that defines a contract for shapes with an area method:

Now we will implement a class. Interfaces can be used to define the expected properties and methods that a class should have.
This establishes a contract that classes implementing the interface must use all the properties and methods interface has.
