You can assign a default value to a function so that it is assigned if you don't explicitly assign anything.

// Parameters with default values
const getHost = function (hostname: string, port: number = 443): string {
  return `${hostname}:${port}`;
};

const localhost = getHost('localhost', 3000);
const yourDomain = getHost('yourdomain.com');

console.log(yourDomain);
