Answer 1

i don't know what exactly you are looking to do but i corrected it a bit to make it work.

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();

Hopefully above helps , otherwise describe your problem in detail .
