Course Overview

Node.js is considered a game changer in web development. Written in JavaScript, it’s the most adopted language, and the only programming language supported natively by every web browser. Once acquainted with Node.js and JavaScript, you can comfortably develop software for a wide variety of platforms. The course starts by explaining the Node.js platform and introduces its ecosystem and philosophy. Next, it introduces the modules system, callbacks and events that help in developing asynchronous applications....Show More
