How to Define a Swift Class in Javascript?

Estimated read time 2 min read

Swift is a programming language that is primarily used for developing applications for Apple’s platforms, such as iOS and macOS. JavaScript is a completely different language, and it is not possible to define a Swift class in JavaScript.

If you are looking to define a class in JavaScript, here’s an example of how you can do it:

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

  sayHello() {
    console.log(`Hello, my name is ${} and I am ${this.age} years old.`);

const john = new Person('John', 30);
john.sayHello(); // "Hello, my name is John and I am 30 years old."

In this example, we define a class called Person using the class keyword. The Person class has a constructor method that takes two arguments, name and age, and sets them as properties on the class instance using the this keyword. The class also has a sayHello method that logs a message to the console using the name and age properties.

We then create a new instance of the Person class called john using the new keyword, and call the sayHello method on the john instance to log a message to the console.

This is an example of how you can define a class in JavaScript, but it is important to note that the syntax and features of JavaScript classes are different from those of Swift classes.
