function contact(name, number) {
this.name = name;
this.number = number;
this.print= this.name+this.number.toString();
}

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

Deleted two last line
And add console.log(ditto👇)

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

console.log(this.name+": "+this.number)
}

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