asynchronous APIs

Asynchronous APIs are a way for software systems to communicate efficiently by allowing a program to send a request and continue working on other tasks without waiting for an immediate response. When the response is ready, it’s sent back separately. This approach helps improve performance and responsiveness, especially when dealing with slow or external services. For example, a weather app might request forecast data from a server and, instead of waiting idle, it can keep updating the display or handle other tasks. Once the data arrives, it updates the weather information seamlessly.
