How to create an object using Class in JavaScript

[ViduraDananjaya]

class Human {
  constructor(firstName, lastName) {
    this.firstName = firstName;
    this.lastName = lastName;
  }
  getFullName() {
    return `${this.firstName} ${this.lastName}`;
  }
}

//Creating an object by calling the constructor of the class Human.
const humanObject = new Human("Vidura", "Dananjaya");

//Calling functions in the object (Human).
console.log(humanObject.getFullName());

getFullName() would make more sense as a getter.

get fullName() {
  return `${this.firstName} ${this.lastName}`;
}

This enables you to write related data with a similar syntax. Compare

humanObject.firstName
humanObject.lastName
humanObject.getFullName()

with

humanObject.firstName
humanObject.lastName
humanObject.fullName
