Update README.md

[Shivamycodee]

I watched the recent FreeCodeCamp video on JavaScript essentials released a month ago. It explains the core concepts very efficiently by building practical tools. I'm confident that incorporating these approaches will be really helpful for new learners.

Description

3. Build Node.js applications with event-driven architecture.

4. Practice async/await for clean asynchronous code.

5. Use ES6 classes and modules for better organization.
