What are the differences between class and prototype in JavaScript?

Can you explain the differences between class and prototype in JavaScript?

Sure! In JavaScript, classes are syntactical sugar over the existing prototype-based inheritance. Classes provide a clearer and more concise way to create objects and handle inheritance.

What are the main advantages of using classes over prototypes?

Classes offer a more structured approach, making the code easier to read and maintain. They also support features like static methods and inheritance more intuitively.

Are there any performance differences between using classes and prototypes?

Generally, there isn't a significant performance difference. However, classes can lead to more optimized code in certain scenarios due to their clearer structure.

Can you give me an example of how to define a class and a prototype?

Absolutely! Here's a simple example:

Using a class:

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

Using a prototype:

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