Classes in ES6

// Classes in ES6

// Classes in ES6 are not hoisted. Also, you can only add methods to classes, not properties.
class Person {
    // Every class must have a constructor
    constructor(name, birthYear, job) {
        this.name = name;
        this.birthYear = birthYear;
        this.job = job;
    }   // no comma here, oddly enough.
    //Methods are added here
    calculateAge() {
        var age = new Date().getFullYear - this.birthYear;
        console.log(age);
    }
    // static class example
    static greetings() {
        console.log('Hey there!');
    }
}

const john6 = new Person ('John', 1990, 'teacher');
Person.greetings(); //static class must be invoked.
