Keyword 'this'

You can refer to the attributes not only outside the class but inside, too, for example, inside methods. To do that, use this keyword. this is like a name of object, but it means the current object, i. e. it refers to the global object.

Let's change current age of the student each time we call happyBirthday() function, and print it:

123456789101112131415
class Student{ name = 'June'; university = 'MIT'; age = 18; gpa; sleep(){ console.log('I am sleeping right now!') } happyBirthday(){ this.age += 1; console.log('Today is my birthday! I am', this.age, 'yrs old!'); } }

Modify happyBirthday() function: output info about new age and about name of the student. After that, create an object of class Student, and call this method three times to see what happens with age.
