Code readability refers to how easily a person can read and understand source code. It involves using clear naming conventions, consistent formatting, and logical structure, which help developers quickly grasp the purpose and functionality of the code. High readability reduces the time needed for debugging and maintenance, making it easier for teams to collaborate. Good practices for enhancing code readability include using meaningful variable names, adding comments where necessary, and organizing code into functions or modules. These techniques not only benefit the original author but also assist others who may work on the code in the future, fostering better collaboration and knowledge sharing.
