CompletableDeferred

CompletableDeferred is a concept from programming, specifically in Kotlin's coroutine framework. It represents a promise that signifies a value will be available in the future. Imagine it as an empty box that you can fill later—it lets you start a task now, and once it’s finished, you can 'complete' the box with the result. This allows other parts of your program to wait for the completion without blocking everything else, enabling smoother and more efficient multitasking in applications, especially for operations that take time, like network requests or file processing.
