Yo I'm doing the contact manager project and I'm supposed to create a print method and it's just confusing

Question

This is all they gave

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

}

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

Then i tried to create a print function to make it output the contacts in the format
Name:number
But it just keeps saying one thing is not defined or missing parentheses and Ive tried sometimes it gives no output so pls I need help cus I been on this for a few days but I haven't got a solution
Also I don't even know if the print is a special word for doing a paticular thing cus when you type it it's colored

Answer 1

Okey first of all you can't just add : through return, that's why you had an error but you can print them out directly as follows:

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

}

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

Oh okay thanks a lot

Answer 3

Could you share your attempt?

Answer 4

Sure

Answer 5

i wonder why would you need another function to print them up when you can print them directly. for eg-: console.log(a, b);

(well. I'm not a JS expert)

Answer 6

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

}
function print(x,y){
return(x: y)
}

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

Answer 7

No I can't print them directly cus ur asked to make a print method to output them like
David: 12345
Amy: 987654321

Answer 8

Besides I tried doing that and it gave contact david 12345
Contact Amy 987654321

Answer 9

When you make a function one of the biggest objectives is not repeating the same code over and over again. An advatnage of this in the long run is that when you want to change the way something behaves in the future, then you only need to change it in one place. Its also good to make your variables have meaningful names so its more readable. So you can do this this to your print func:

function print(contact) {
console.log(contact.name + “: “ + contact.number)
}

var david = new contact(“David”, 12345)

print(david)
