Web Development with Node.JS and MongoDB (Video 3)

This video delves deeper into Node JS, explaining its single-threaded nature and how it handles blocking and nonblocking code. It uses a breakfast analogy to illustrate nonblocking IO operations. The video also covers the call stack, its structure, and its importance in debugging. Additionally, it provides guidance on writing command-line scripts in Node JS, including handling arguments and exit codes. The video concludes with a preview of setting up a development environment in the next session.
