An essential step in the software development lifecycle is code review. It enables developers to significantly enhance code quality. It resembles the authoring of a book. The story is written by the author, but it is then edited to ensure no mistakes like mixing up "you're" with "yours." Code review, in this context, refers to examining and assessing other people's code.
There are different ๐ฏ๐ฒ๐ป๐ฒ๐ณ๐ถ๐๐ ๐ผ๐ณ ๐ฎ ๐ฐ๐ผ๐ฑ๐ฒ ๐ฟ๐ฒ๐๐ถ๐ฒ๐: it ensures consistency in design and implementation, optimizes code for better performance, is an opportunity to learn, and knowledge sharing and mentoring, as well as promotes team cohesion.
What to look for in a code review? Try to look for things such as:
๐น๐๐ฒ๐๐ถ๐ด๐ป (does this integrate well with the rest of the system, and are interactions of different components make sense)
๐น๐๐๐ป๐ฐ๐๐ถ๐ผ๐ป๐ฎ๐น๐ถ๐๐ (does this change is what the developer intended)
๐น๐๐ผ๐บ๐ฝ๐น๐ฒ๐ ๐ถ๐๐ (is this code more complex than it should be)
๐น๐ก๐ฎ๐บ๐ถ๐ป๐ด (is naming good?)
๐น๐๐ป๐ด. ๐ฝ๐ฟ๐ถ๐ป๐ฐ๐ถ๐ฝ๐น๐ฒ๐ (solid, kiss, dry)
๐น๐ง๐ฒ๐๐๐ (are different kinds of tests used appropriately, code coverage)
๐น๐ฆ๐๐๐น๐ฒ (does it follow style guidelines)
๐น๐๐ผ๐ฐ๐๐บ๐ฒ๐ป๐๐ฎ๐๐ถ๐ผ๐ป, and more
Here are some good practices when doing a code review:
๐ญ. ๐ง๐ฟ๐ ๐๐ผ ๐ฟ๐ฒ๐๐ถ๐ฒ๐ ๐๐ผ๐๐ฟ ๐ผ๐๐ป ๐ฐ๐ผ๐ฑ๐ฒ ๐ณ๐ถ๐ฟ๐๐
Before sending a code to your colleagues, try to read and understand it first. Search for parts that confuse you.

This should explain what changes were at a high level and why those changes were made.
๐ฏ. ๐๐๐๐ผ๐บ๐ฎ๐๐ฒ ๐๐ต๐ฎ๐ ๐ฐ๐ฎ๐ป ๐ฏ๐ฒ ๐ฎ๐๐๐ผ๐บ๐ฎ๐๐ฒ๐ฑ
Leave to the system everything that can be automated, such as checking for successful builds (CI), style changes (linters), automated tests, and some code smells and bugs (SonarQube).
๐ฐ. ๐๐ผ๐ป'๐ ๐ฟ๐๐๐ต
You need to understand what has changed. Every line of it. Read multiple times if needed, class by class.
๐ฑ. ๐๐ผ๐บ๐บ๐ฒ๐ป๐ ๐๐ถ๐๐ต ๐ธ๐ถ๐ป๐ฑ๐ป๐ฒ๐๐
Never mention the person (you), always focus on changes as questions or suggestions, and leave at least one positive comment. Explain the "why" in your comments and give a suggestion on how to make it better.
๐ฒ. ๐๐ฝ๐ฝ๐ฟ๐ผ๐๐ฒ ๐ฃ๐ฅ ๐๐ต๐ฒ๐ป ๐ถ๐๐ ๐ด๐ผ๐ผ๐ฑ ๐ฒ๐ป๐ผ๐๐ด๐ต
Don't strive for perfection, but hold to high standards. Don't be a nitpicker.

We should limit the number of lines of code for review in one sitting. Our brains cannot process so much information at once. The ideal number of LOC is 200 to 400 lines of the core at one time, which is usually 60 to 90 minutes.
What is your code review process? What works for you, and what does not?
