Overview
The Gilded Rose Kata and other code katas are popular because they offer developers the opportunity to learn code skills in a practical way. They are also often used to test developers as part of the take-home challenge in the interview process. Often you’re working with code you didn’t write yourself, yet you need to make sense of it quickly so you can add a new feature or fix a bug. This course will show you how to use the tools you have available in your IDE to rapidly read and understand various varieties of awkward code, at the same time as safely improving the design. We’ll also go through some common Object Oriented designs to use when your code is missing important abstractions.
By making small safe design improvements as you read code, you gain better understanding and control of unfamiliar code and also leave it in a better state for the next reader. The important thing to remember is to do it in safe small steps and make good use of automated tools. This course will help you to improve your code, your use of your IDE, and your design skills.
What you’ll learn and how to apply it
By the end of the course, learners should be able to
- Use code-reading techniques like scanning, code folding and highlight usages.
- Identify when to use common refactorings like extract method, introduce parameter and introduce variable.
- Recognize safe refactoring techniques and explain when and why they would use them.
- List suitable OO designs to move towards when refactoring.
This course is for you because
- You are a programmer interested in learning to design better code.
- You are looking to move into a new role from junior developer to more senior developer.
- You want to become more proficient at using your IDE tools including refactoring.
- You want to get better at OO design.
