constructors in javascript classes code example

Example 1: javascript class constructor

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

const person = new Person("John Doe", 23);

console.log(person.name); // expected output: "John Doe"

Example 2: constructors javascript

function Bird() {
  this.name = "Albert";
  this.color = "blue";
  this.numLegs = 2;
}
/*
This constructor defines a Bird object with properties name, color, and
numLegs set to Albert, blue, and 2, respectively.
Constructors follow a few conventions:
-Constructors are defined with a capitalized name to distinguish them from
other functions that are not constructors.

-Constructors use the keyword this to set properties of the object they will
create. Inside the constructor, this refers to the new object it will create.

-Constructors define properties and behaviors instead of returning a value as
other functions might.
