Chapter 13 Robot game solution (p. 583 in pdf book)

Hello,

Why is a function needed under the unlock function? The following doesn't work... why doesn't it?

Game.prototype.unlock = function() { if (this.level === 42) { console.log(this.name + " is blasting you with laser beams."); } }

...

robby.unlock(); rosie.unlock();

because we don't want lasers only at level 42; we want lasers for all robots that reach level 42 so they keep them after that too. By adding the function to the prototype, you can call deployLaser after you've reached level 42 and gone beyond.

Ok, I can wrap my head around that. Thank you for the prompt responses (again)!
