Classes in TypeScript

Question

I am currently learning TS and I wanted to see if I understand the following. I know that a class in TS can include a property, a constructor, and a method. We are creating a new object with new Greeter, and running the constructor to initialize it with "world".

class Greeter {  
greeting: string;  

constructor(message: string) {  
this.greeting = message;   
}  

greet() {  
return "Hello, " + this.greeting;   
  } 
} 
let greeter = new Greeter("world");

Yes, the constructor assigns the value "world" to the 'greeting' property of the new object 'greeter'.

console.log(greeter.greet())

will console log as:

Hello, world
