We spend more time reading our code than writing it. So doesn’t it make sense that our code is clean, precise and easy to read? In this session we discuss how to take a code written in a hurry and apply best practices to refactor and clean it up. We will take a messy piece of code and step by step clean it up.

Why Clean Code?

Why do we need clean code? Bad code works too! Don’t fix what is not broken.

Code following best practices

• Easy to understand by other developers : readable by developers other than the one who developed it.
• Easy to maintain : lower chances of accidentally introducing bugs
• Modified without fear of breaking anything : Lot of developers take great pride in making the code compact – trying to do multiple things on one line – which might be impressive, but makes the code much harder to read and understand

Where do we begin ?

Clean code always looks like it was written by someone who cares.

Clean Code rules

• Keep your methods short
• Don’t repeat yourself
• Methods should do just one thing
