This course is designed to teach Node.js from complete beginner level to production-ready backend development.
The main goal is to understand how Node.js works internally, how backend applications are built, and how Node.js connects with React to create complete MERN stack applications.
This course focuses more on concept clarity, internal working, real project usage, and industry practices rather than only learning syntax.
