What is the difference between classes and constructors in JavaScript?

In JavaScript, classes are syntactical sugar over constructor functions. Classes provide a clearer and more concise way to create objects and handle inheritance.

Can you give me an example of a class and a constructor?

Sure! Here's a simple example:

// Constructor function function Person(name) { this.name = name; }

// Class syntax class Animal { constructor(type) { this.type = type; } }

Both can be used to create objects, but classes offer more features like inheritance.

What are the advantages of using classes over constructors?

Classes provide a clearer syntax, support inheritance more intuitively, and allow for static methods. They also help in organizing code better.

Are there any downsides to using classes?

One downside is that classes can be less flexible than constructor functions in certain scenarios. Additionally, they may introduce a slight performance overhead.
