Future

In computer science, a "Future" is a construct that represents a value that may not yet be computed or available. It serves as a placeholder for a result that is expected to be available at some point in the future, enabling asynchronous programming and concurrent execution. A Future allows a program to initiate a task and continue executing other operations without waiting for the task to complete.Once the computation is finished, the Future can provide access to the computed result, or indicate if an error occurred during processing. This mechanism is particularly useful in multi-threaded environments, where one thread can perform operations while another thread is responsible for computing a result.Futures are commonly used in various programming languages and frameworks, often accompanied by promises, which are similar constructs that represent the eventual completion (or failure) of an asynchronous operation. Together, these concepts help manage concurrency and simplify the handling of asynchronous results.
