(WS14) Sasa Matijasic - Node.js i "novi" web
0 likes698 views
Node.js is a cross-platform JavaScript runtime environment that allows for building server-side and networking applications. It uses Google's V8 JavaScript engine and supports asynchronous programming which makes it suitable for data-intensive real-time applications that run across distributed devices. Some key advantages are that it is fast, supports many concurrent connections, and has a large ecosystem of libraries available through npm. However, it is still maturing and relies on JavaScript.
