2: Dead Code

Delete it

If the code doesn't get executed, just delete it.

Deleting dead code can be strange

• Someone took the time & effort to write it.

• The organization paid for it.

• All somebody needs to do to make it valuable is to call it again.

• If we need it, we'll be sad we deleted it.

How many cognitive biases are in the reasons above?

What if we need it later?

We have Version Control. If worse comes to worst, we can always get it back.

Or, we can just write it again, but better. What's the likelihood we will use it again in exactly the same way it was originally written?
