Async

Async, short for asynchronous, refers to a way computers handle tasks without waiting for each one to finish before starting the next. Imagine cooking multiple dishes at once—while the oven bakes, you prepare a salad. Similarly, in programming, async allows a program to initiate a task (like fetching data from the internet) and move on to other tasks without delay. When the data is ready, the program gets notified and handles it. This approach improves efficiency and responsiveness, especially when dealing with slow or unpredictable operations, making software faster and more efficient.
