Help me to solve this javascript test in the javascript course. I already wrote the code but what's wrong in the code .

Question

Question
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.

My code
function contact(name, number) {
this.name = name;
this.number = number;
this.print = print1;
}
function print () {
return
console.log(this.name ":" this.number);

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

Answer 1

Your Mistakes

1. this.print = print1 ;
^
print1 is not define

2. Using this.print() = function(){...}
(inside contact function)

3. U should write
console.log(this.name + ":" + this.number )

4. Don't using a.print() inside document.write()

Full code :

function contact(name, number) {
this.name = name;
this.number = number;
//this.print = print1;
this.print = function(){
console.log(this.name+ ":" +this.number);
}
}
/*function print () {
return console.log(this.name ":" this.number);

}*/
var a = new contact("David", 12345);
var b = new contact("Amy", 987654321);
//document.write(a.print());
//document.write(b.print());
a.print()
b.print()

Answer 2

this.name ":" this.number

You need to concatenate these three things via an operator, you cant just write them after each other. In javascript string concatenation is done with the + operator.

Also, as Beauty said, remove document write

Answer 3

Thank you so much

Answer 4

Thanks for clearing this up for me as well!

Answer 5

I redid the code as you indicated, but I am not getting the spaces, so I keep getting an error
