The CircleCI's annual State of Software Delivery report reveals key trends and insights in programming languages and their impact on software delivery performance, based on data from over 14 million workflows. As CI/CD and DevOps become integral to organizations aiming for efficient delivery cycles, programming language choices influence developer productivity and performance metrics such as workflow duration, throughput, mean time to recovery, and success rate. The report highlights the growing popularity of languages like Python, TypeScript, and C# due to their support for rapid, scalable, and secure development across various applications, including machine learning, enterprise systems, and cross-platform development. Python has surged in usage thanks to its versatility and powerful libraries for AI and data science, while TypeScript has maintained its dominance over JavaScript for building complex applications. C# continues to gain traction for its cross-platform capabilities and integration with Microsoft's ecosystem. This data underscores a shift towards languages that offer a blend of speed, security, and scalability, contributing to faster error recovery and improved software delivery performance.
