How can one ensure that sub-classes have uniform method parameters in TypeScript?

One way to ensure that sub-classes have uniform method parameters in TypeScript is by using an abstract class with an abstract method. Abstract classes cannot be instantiated directly and must be subclassed. The abstract method in the abstract class can define the uniform method parameters that sub-classes must implement. Here's an example:

abstract class Animal {
  abstract makeSound(sound: string): void;
}

class Dog extends Animal {
  makeSound(sound: string) {
    console.log(`Bark: ${sound}`);
  }
}

class Cat extends Animal {
  makeSound(sound: string) {
    console.log(`Meow: ${sound}`);
  }
}

const dog = new Dog();
dog.makeSound('woof'); // outputs "Bark: woof"

const cat = new Cat();
cat.makeSound('purr'); // outputs "Meow: purr"

In the above example, the Animal abstract class defines the makeSound method with a sound parameter. Both the Dog and Cat classes must implement the makeSound method with a sound parameter, ensuring uniformity across sub-classes.
