Web Development with Node.JS and MongoDB (Video 2)

This video tutorial introduces Node.js, an asynchronous event-driven framework built on Chrome's V8 JavaScript engine. It covers the basics, including its lightweight and efficient nature, making it ideal for scalable network applications. The tutorial explains Node.js's single-threaded model, event loop, and non-blocking design. It highlights use cases like real-time web applications and APIs for noSQL databases, while also discussing limitations such as CPU-intensive tasks and relational databases. The video concludes with a summary and a preview of upcoming topics like blocking vs nonblocking code.

What makes Node.js a great choice for building scalable network applications?

• Its lightweight and efficient design

• Its compatibility with relational databases

• Its synchronous event-driven framework

• Its multi-threaded architecture

How does Node.js handle concurrent operations efficiently?

• By using multiple threads

• By blocking the program

• By using synchronous functions

• By registering a callback and continuing

What is the purpose of a callback function in Node.js?

• To share the scope with other modules

• To block the execution of code

• To handle errors synchronously

• To be invoked once an asynchronous function has a response

In which scenario does Node.js excel?

• Real-time web applications

• Single-user desktop applications

• CPU-intensive operations

• Working with relational databases

Why might Node.js not be suitable for applications requiring relational databases?

• It is not efficient for handling multiple connections

• It doesn't work well with relational databases

• It is too lightweight for such tasks

• It lacks support for asynchronous operations
