Answer 1

A constructor in typescript (or javascript and many other OOP languages), is the method of a class that is called when an instance of the class is created.

class Example {
constructor(param: string) {
alert('received param: ' + param);
}
}

new Example('hello'); // alerts "received param: hello"
