JavaScript

JavaScript is the sole native programming language of the web browser, created by Brendan Eich in just 10 days in 1995, yet it now runs on over 97% of all websites. Its dominance surpasses that of #1 C in ubiquity, powering both client-side interactions and server-side logic through Node.js, which handles 20,000+ npm packages and processes over 1 billion downloads per week. JavaScript outperforms the average web language with its event-driven, non-blocking I/O model, enabling real-time applications like chat and gaming with 200% faster response times than traditional approaches. Frameworks like React (used by 40% of professional developers) and Angular drive modern single-page applications, making JavaScript the only language capable of running across the full web stack—from frontend to backend to database. Its influence extends to mobile development via React Native and desktop apps through Electron, solidifying JavaScript's role as the universal glue of the internet.
