What are the differences between ES6 classes and constructor functions?

What are the differences between ES6 classes and constructor functions?

ES6 classes provide a clearer syntax and are syntactical sugar over JavaScript's existing prototype-based inheritance. Constructor functions, on the other hand, are the traditional way to create objects and manage inheritance.

Can you give me an example of each?

Sure! Here's a constructor function:

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

And here's an ES6 class:

class Person {
    constructor(name) {
        this.name = name;
    }
}

Are there any advantages to using ES6 classes?

Yes, ES6 classes offer a more intuitive syntax, support for static methods, and better handling of inheritance, making the code easier to read and maintain.

What about the performance differences?

In terms of performance, there isn't a significant difference between the two. The choice often comes down to readability and maintainability rather than speed.
