Code review practices are evolving as more developers utilize AI coding assistants like ChatGPT and GitHub Copilot, leading to an increased volume of code that requires review. An analysis of over 5 million pull requests reveals that small companies, defined as those with 20 or fewer engineers, merge code three times faster than larger organizations, partly due to their tendency to skip code reviews. TypeScript is increasingly favored over JavaScript at smaller startups, while larger companies continue to use established languages like Java and Python. Companies employing monorepos experience significantly longer merge times, while the ideal pull request (PR) size for efficiency is found to be 50 lines or fewer. Continuous Integration (CI) run times are notably longer at larger companies, which also are more likely to use merge queues to automate and streamline the merging process. Overall, the findings suggest that while smaller companies benefit from speedier processes, larger organizations prioritize thoroughness and complexity management.
