JavaScript Object-Oriented JavaScript Working with Classes in JavaScript Adding Methods To Our Class

I don't quite understand why do we need to use the method here in the class syntax?

class Pet { constructor(animal, age, breed, sound) { this.animal = animal; this.age = age; this.breed = breed; this.sound = sound; }

speak() { console.log(this.sound); }

class Student { constructor(gpa){ this.gpa = gpa; } stringGPA() { return this.gpa = "gpa"; } } const student = new Student (3.9);

What happens if we don't use the method?

Are you asking why we use the new Student(3.9) syntax?

Hello Hanwen,

Functions or methods are used to break your code into smaller parts. When you write a large program you can work on one method at a time to make sure it works properly.

If you do not use methods, you just have one program that does everything.

I hope this is helpful to you.
