TypeScript Method Overriding

Method Overriding -

In Method Overriding, redefined the base class methods in the derive class or child class.

class NewPrinter extends Printer {
    doPrint(): any {
        super.doPrint();
        console.log("Called Child class.");
    }

    doInkJetPrint(): any {
        console.log("Called doInkJetPrint().");
    }
}

let printer: new () => NewPrinter;
printer.doPrint();
printer.doInkJetPrint();
