JavaScript Classes Explained Simply

ES6 syntactic sugar that allows us to program in a more object-orientated way. It allows us to define a constructor together with its prototype methods.

class Lesson {
  constructor(title) {
    this.title = title;
    this.completed = false;
  }
  complete() {
    this.completed = true;
    return this.title + " complete";
  }
}

const lesson = new Lesson("Closures");
console.log(lesson.complete());
console.log(lesson.completed);
