Javascript contact Manager Module Project

Question

I don't understand why my code isn't working. I tried it on my computer and the output works but in the app it doesn't work
🔹🔹🔹🔹🔹
❓You are working on a Contact Manager app.
You have created the contact object constructor, which has two arguments, name and number.
You need to add a print() method to the object, which will output the contact data to the console in the following format: name: number
The given code declares two objects and calls their print() methods. Complete the code by defining the print() method for the objects.
🔻🔻🔻🔻🔻
function contact(name, number) {
this.name = name;
this.number = number;
this.print = function () {
this.output = this.name + ":" + this.number;
}
}

var a = new contact("David", 12345);
var b = new contact("Amy", 987654321)
a.print();
b.print();

Answer 1

function contact(name, number)
{
this.name = name;
this.number = number;
this.print = function() {
console.log(this.name+": "+this.number);
}
}

var a = new contact("David", 12345);
var b = new contact("Amy", 987654321)
a.print();
b.print();

Here is my code.
You can try it.
Happy coding 👍

Answer 2

function contact(name, number) {
this.name = name;
this.number = number;

this.print = function (){
console.log(this.name + ": " + this.number);}
}

var a = new contact("David", 12345);
var b = new contact("Amy", 987654321);
a.print();
b.print();

Spentify thank you! 😊👍

Answer 4

function contact(name, number) {
this.name = name;
this.number = number;
this.print = function () {
console.log(name+": "+ number);
}
}
var a = new contact("David", 12345);
var b = new contact("Amy", 987654321);
a.print();
b.print();

Answer 5

function contact(name, number) {
this.name = name;
this.number = number;

this.print = print;
}
function print() {
console.log(this.name + ": " + this.number);
}

var a = new contact("David", 12345);
var b = new contact("Amy", 987654321);
a.print();
b.print();

Note: there must be a space after the colon (:).
This ": " Space in the string.
Not ":" No space in string.

This will solve the project, but try both to see how it works.
Happy coding!
