Asynchronous JavaScript

Asynchronous JavaScript allows a program to perform multiple tasks at once without waiting for each to finish before moving on. Think of it like ordering food: you place your order and then do other things while the kitchen prepares it. In programming, this means a webpage can keep responding to your clicks or updates while fetching data in the background. This improves efficiency and user experience, preventing delays or freezing. Techniques like callbacks, promises, and async/await manage these tasks, enabling smooth, responsive interactions even when running complex or time-consuming operations.
