Asynchronous Basics

This video tutorial introduces asynchronous programming in Node.js, highlighting its non-blocking nature. It begins with a basic example using setTimeout to demonstrate asynchronous behavior. The tutorial then guides viewers through setting up a weather app project, explaining the order of execution in asynchronous programming. Advanced concepts are introduced, preparing viewers for making HTTP requests to fetch real-time weather data.

What does it mean for a Node.js application to be asynchronous and non-blocking?

How does asynchronous programming improve the efficiency of a Node.js application?

What is the purpose of the setTimeout function in Node.js?

Explain the difference in execution order between synchronous and asynchronous programming in Node.js.

Why is it beneficial for Node.js to handle multiple database requests simultaneously?

What happens when you add multiple setTimeout calls with different delays?

What will be the output order when using both a 0 millisecond and a 2 second timer in a Node.js application?
