Real-time collaborative tools like Google Docs use JavaScript with WebSocket connections to synchronize document edits across multiple users simultaneously with sub-second latency.

Case Study

JavaScript was created in just 10 days by Brendan Eich at Netscape in 1995. Despite its rushed creation, it became the world’s most-used programming language. With Node.js (2009) enabling server-side JavaScript and frameworks like React (2013), JavaScript now powers both frontend and backend of applications used by billions of people daily.
