TypeScript Becomes GitHub’s Most Popular Programming Language
TypeScript has officially taken the lead as the most widely used programming language on GitHub, according to new data from the platform’s Octoverse 2025 report. The milestone highlights a major shift in software development priorities driven by the growing integration of artificial intelligence into everyday coding practices.
A Changing Landscape in Programming
For the first time, in August 2025, TypeScript surpassed both JavaScript and Python in GitHub usage statistics. The trend signals the software industry’s increasing preference for statically typed languages that offer improved reliability and compatibility with AI-assisted development tools.
GitHub’s analysis attributes this transition to the evolution of developer workflows. Many popular front-end frameworks—such as React, Angular, and Vue—now default to TypeScript when generating new projects. This widespread adoption has accelerated the language’s growth across web, mobile, and even backend environments.
Although Python continues to dominate data science and artificial intelligence research, overall coding activity has shifted more heavily toward the JavaScript–TypeScript ecosystem, where developers combine AI integration with large-scale application development.
AI’s Expanding Influence
TypeScript’s rise is only one of several major transformations outlined in GitHub’s report, all closely tied to the surge in AI-powered coding. Over 1.1 million public repositories now include large language model (LLM) integrations or SDKs, and more than 690,000 of these were created within the past year alone.
Developer activity also reached unprecedented levels in 2025. GitHub users merged over 518 million pull requests, representing a 29% increase compared with the previous year. Notably, a growing share of this work involved automated code generation and AI-assisted contributions. Among new GitHub users, eight out of ten activated Copilot—the AI code completion tool—during their first week on the platform.
AI Reshaping Developer Behavior
Beyond accelerating coding speed, artificial intelligence is also changing how developers make choices about their tools. In earlier years, selecting a language or framework was a purely technical decision. Now, the capabilities of AI systems are shaping those preferences, with developers gravitating toward languages that integrate smoothly with AI agents and automation frameworks.
GitHub’s internal data suggests that this shift is only the beginning. The company expects even greater adoption of agent-based workflows, where autonomous coding assistants take on larger roles in project creation and maintenance.
Record Year for Repository Activity
The Octoverse 2025 findings also reflect the overall explosion of AI-related work on GitHub. More than 4.3 million repositories now focus on artificial intelligence topics, and developers are creating new projects at record speed—around 230 every minute. Monthly averages show over 43 million pull requests merged and nearly one billion commits pushed in 2025, a 25% year-over-year growth.
August alone set a new milestone, with developers submitting nearly 100 million commits—underscoring both the intensity of global collaboration and the accelerating impact of AI in software engineering.
