Does JavaScript have classes?

Technically, the statement "JavaScript has no classes" is correct.

Although JavaScript is object-oriented language, it isn't a class-based language—it's a prototype-based language. There are differences between these two approaches, but since it is possible to use JavaScript like a class-based language, many people (including myself) often simply refer to the constructor functions as "classes".

Javascript is an object oriented programming language, nevertheless in 2015 with ECMA script 6 classes have been introduced and now is correct to use them like other class based languages like Java. Of course as pointed out by the user codemagician in his/her comment, there are some deep differences between how classes work in js and java or other "class based" programming languages.

Nevertheless now in js programming it is possible to use for example code like:

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


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

That has something in common with classical class-based languages. The problems still is the browser support of this new technology that is just at start at the moment. So it still is not good to use it on productions products. But I don't have any doubt that this issue is going to be solved fast.

Hence the question remains if js has become a class-based programming language because of the implementation of this new features or does it still remain an object prototyping oriented programming language.
