What is the “get” keyword before a function in a class?

Question

What does get mean in this ES6 class? How do I reference this function? How should I use it?

class Polygon {
  constructor(height, width) {
           


        

Answer 1

or more simple way it just call the function without needing to user "()" just by typing the function name

the two above function are equal attention to person.fullName() and person.fullName

const person = {
    firstName: 'Willem',
    lastName: 'Veen',
    fullName() {
        return `${this.firstName} ${this.lastName}`;
    }

}

console.log(person.fullName());

const person = {
    firstName: 'Willem',
    lastName: 'Veen',
    get fullName() {
        return `${this.firstName} ${this.lastName}`;
    }

}

console.log(person.fullName);
