Reusing Code

All developers write code (or should write code) with reuse in mind. The many reasons this is a good idea include:

• Saving time— If it is written once, don't write it again.

• Easier maintenance— Make a change in one place and any code that uses it gets that change automatically.

• Easier debugging— Fewer copies exist out there that will need to be fixed.

• Group development— Developers can share code more easily.
