But when you are shooting at werewolves, silver bullets are definitely the thing to use.
A while back, I had an application which needed to do some fairly complicated string manipulation, both on the client side and the server side, and by using Node, I was able to write and debug that code once. There are good use cases here.
I always thought that it was because in the metaphor the "werewolf" was "programming is hard". There is no silver bullet to kill the "I have to make trade-offs as this gets more complex!" monster.
I could be wrong, I have no reference or even a memory of learning this so I have either forgotten or I just made this up.
Silver's way more expensive than lead and offers little or no improvement unless you're shooting at werewolves.
