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.
