How to use ES6 Classes In Javascript

To create a struct-like object using ES6 classes, you define a class using the class keyword, followed by the class name. Inside the class, you define a constructor method to initialize the object’s properties and methods. After defining, you can create instances of the class using the new keyword. You can access and manipulate the properties of it using dot notation.

Example: Explanation of Structs in JavaScript Using ES6 Classes.

JavaScript

class Person {
    constructor(name, age, occupation) {
        this.name = name;
        this.age = age;
        this.occupation = occupation;
    }

    // Method to display person's details
    displayDetails() {
        console.log(`Name: ${this.name}, Age: ${this.age},
                     Occupation: ${this.occupation}`);
    }
}

// Creating an instance of Person
const person1 = new Person('John Doe', 30, 'Engineer');
const person2 = new Person('Jane Smith', 25, 'Doctor');

// Accessing properties
console.log("Name:", person1.name); 
console.log("Age:", person2.age);

// Updating properties
person1.name = 'Ram';
person2.age = 45;

// Calling method to display details
person1.displayDetails();
person2.displayDetails();

Output

Name: John Doe
Age: 25
Name: Ram, Age: 30, Occupation: Engineer
Name: Jane Smith, Age: 45, Occupation: Doctor

How to work with Structs in JavaScript ?

Structs are typically found in languages like C, C++, and similar, and they provide a way to organize related data items under one name. Typically JavaScript does not have built-in support for structs, but you can achieve similar functionality using objects. Objects in JavaScript are dynamic collections of key-value pairs, where keys are strings (or Symbols) and values can be any data.
