Class PrinterAbstract

Example

Example demonstrating implementing a custom Printer class and defining a plain object conforming to Printer

// 1. Implementing as a class
class CustomPrinter extends Printer {
  override toString(): string {
    return "Hello from CustomPrinter";
  }
}

const printerObj = new CustomPrinter();
console.log(printerObj.toString()); // "Hello from CustomPrinter"

// 2. Conforming as a plain object
const plainPrinter = {
  toString: () => "Hello from plain object",
} satisfies Printer;

console.log(plainPrinter.toString()); // "Hello from plain object"
