Welcome to an engaging exploration of code reviews in software engineering! In this article, we’ll delve into the insights shared by industry professionals and students, highlighting the significance of code reviews in the software development process.
Our journey begins with insights from Gemma Bissoni, CEO of Discover Labs, Javon, a Computer Science student at the University of Washington, Seattle, Levar, a Software Engineering Manager at Airbnb, and Pan, a Software Engineer at Xbox. Each brings a unique perspective on the importance of code reviews.
One of the critical steps in software development is refining and debugging code. Code reviews play a pivotal role in this process. They involve examining code to identify improvements and fix existing issues. This collaborative effort allows developers to leave comments and engage in discussions with the original code authors, ensuring the code’s success and the product’s quality.
Code reviews are essential because they help developers spot errors that might have been overlooked. Over time, this practice leads to better code quality and an improved codebase. As developers engage in code reviews, they witness their coding skills evolve, resulting in more efficient and robust software.
In practical terms, when developers check in code using platforms like Git, they create a pull request. This request must be approved by at least one other person, making it a powerful learning tool. The process begins with running the code to ensure functionality, followed by a thorough review. During this review, developers look for common errors, assess the code’s logic, and evaluate its efficiency. They also consider potential issues that could arise from future updates.
Code reviews are akin to proofreading. Writing code that is easily readable and well-commented accelerates the understanding process for others. It’s crucial to clearly convey instructions to the computer, ensuring that the code performs as intended.
Code reviews are not just about improving code; they are a valuable learning opportunity. They enhance both the code and the developer’s skills. If you have a skilled code reviewer on your team, seize the chance to collaborate and learn from them. Code reviews bring diverse perspectives, as engineers from different teams contribute their expertise. This diversity enriches the code and fosters a collaborative environment.
Writing code that others can easily understand is vital because software development is a team effort. You won’t always be working on the same task, so your code should be accessible to others. This is the essence of code reviews—ensuring that your work is comprehensible and maintainable by anyone who might work on it in the future.
In conclusion, code reviews are an integral part of software engineering, offering a platform for learning, collaboration, and continuous improvement. Embrace this practice to enhance your coding skills and contribute to the success of your projects.
Engage in a simulated code review session with your peers. You’ll be assigned a piece of code to review, and you’ll provide constructive feedback. This activity will help you practice identifying errors and suggesting improvements, enhancing your understanding of the code review process.
In this activity, you’ll take on different roles such as the code author, reviewer, and observer. By switching roles, you’ll gain insights into each perspective, understanding the importance of clear communication and collaboration during code reviews.
Study a real-world code review from an open-source project. Examine the comments and changes suggested by reviewers. This will provide you with a practical example of how code reviews are conducted in professional settings and the types of issues commonly addressed.
Pair up with a classmate to review each other’s code. Focus on readability, logic, and efficiency. This peer review will help you develop a critical eye for code quality and learn how to give and receive feedback effectively.
Write a reflection on your experiences with code reviews, either from this course or previous experiences. Consider what you’ve learned, how your skills have improved, and how you can apply these lessons to future projects.

Hi everybody, my name is Gemma Bissoni, and I’m the CEO of Discover Labs.
I’m Javon, and I’m a Computer Science student at UW Seattle.
I’m Levar, and I’m a Software Engineering Manager at Airbnb.
My name is Pan, and I am a Software Engineer at Xbox.
One of the most important steps in pushing code is looking for ways to improve it or debug any existing problems. You can leave comments and have conversations with the person who wrote the original code. Code reviews are important because they ensure the success of your code and your product. We don’t always see our own errors as time goes on. I could see the evolution; I was writing better code, and the overall codebase improved each time.
Every time I check in code on Git, I make a pull request, which must be approved by at least one person. It’s a powerful teaching tool. First, we run the code to ensure everything works, and then we sit down to review it. I look for common errors depending on the language, how it’s running, and anything that could potentially be broken if something gets updated. I also focus on logic, learning more about the algorithm, efficiency, and any tests that could break the program.
Code reviews are a great way to learn—not the only way, but a valuable one. They improve both the code and the person writing it. Think of it as proofreading; writing code that is easily readable and well-commented makes it faster for others to understand what’s happening. It’s essential to understand what you are instructing the computer to do.
If you have someone on your team who is a skilled code reviewer, take the opportunity to work with them and listen. Code reviews bring in different perspectives, as you have engineers from various teams who manage different parts of the code. You need to write in a way that someone else can pick it up because you won’t be working on a single task forever. That’s what code review is about.
