Overview
Why learn Node.JS?
Node.JS was developed by Ryan Dahl in 2009 as a powerful framework developed on Chrome’s V8 Javascript engine that compiles the native machine code. It is a lightweight framework which is commonly used in order to develop large-scale applications, especially single-page applications, video streaming sites, etc.
It was first implemented in the year 2011 and since then its popularity has overwhelmed the entire community of developers across the world. The unparallel scalability is the major reasons which encourage major companies like Cisco, Uber, Microsoft, IBM, Netflix, PayPal, and LinkedIn to use it during production. For instance, it improves the load time of Netflix by 70%.
Today, the demand for Node.JS course has increased rapidly. It emphasizes on various concepts and also provides hands-on experience in building HTTP server with Node.JS and multi-processing in Node.JS. Taking up the Node.JS course will enable the participants to build real-time, high performance, and scalable applications. The average salary for "Node.JS developer" ranges from approximately $76,438 per year for Web Developer to $122,918 per year for Senior Software Engineer. The average salary for Node.js developers is comparatively better than professionals proficient other technologies.
