Javascript object creation using literals vs custom constructor functions

Question

I understand that there are multiple ways to create an object in javascript and I have been reading that object literal syntax is generally preferred. (Correct?)

You can use the custom constructor function when you want to create instances of objects, similar to Java.

For example:

function MyObj(x){
   this.x = x;
}

MyObj.prototype.printX = function(){
   alert(this.x);
}

var obj1 = new MyObj("hello");
var obj2 = new MyObj("hello2");
obj1.printX();//prints hello
obj2.printX();//prints hello2

Now I have two instances of this object. If I used String literals I would need to clone the object into a new var in order to get another instance.
