What are JavaScript classes?

Can you explain what JavaScript classes are?

Sure! JavaScript classes are a syntactical sugar over JavaScript's existing prototype-based inheritance. They provide a clearer and more concise way to create objects and handle inheritance.

How do you create a class in JavaScript?

You can create a class using the class keyword. For example:

class Animal {
  constructor(name) {
    this.name = name;
  }
  speak() {
    console.log(`${this.name} makes a noise.`);
  }
}

What is the difference between a class and a function in JavaScript?

A class is a blueprint for creating objects, while a function is a block of code designed to perform a particular task. Classes can encapsulate data and behavior, whereas functions are typically used for executing code.

Can you give me an example of inheritance using classes?

Certainly! Here's an example:

class Dog extends Animal {
  speak() {
    console.log(`${this.name} barks.`);
  }
}

const dog = new Dog('Rex');
 dog.speak(); // Rex barks.
