DRY — Don’t repeat yourself

The DRY principle recommends not to repeat the same solution.

This applies to repeat this code, how to solve it, and what to do. Repetitive actions can be automated, repetitive code can be extracted and referenced, repetitive patterns can be generalized. The advantage of using the DRY principle is that you avoid mistakes and save time:

• The error in the code copied in many places needs to be corrected everywhere.
• When performing a task manually, it’s easy to make a mistake. The automatic script will not make a mistake with subsequent performances and does the work for us.
