Is there a difference between the two codes below, I presume not.

```
function Agent(bIsSecret)
{
    if(bIsSecret)
        this.isSecret=true;

    this.isActive = true;
    this.isMale = false;
}

```

and

```
function Agent(bIsSecret)
{
    if(bIsSecret)
        this.isSecret=true;
}

Agent.prototype.isActive = true;    
Agent.prototype.isMale = true;

```
