• What programming languages support Futures. Answer in MediaWiki syntax with the URL of the official documentation for each language reference.

Futures are a construct used in programming for asynchronous computation. They represent a value that may become available at some point in the future and are a key part of concurrent and parallel programming systems. Below is a list of programming languages that support futures, formatted in MediaWiki syntax, including the URL of the official documentation for each language's futures or equivalent feature.

Dart uses Futures extensively for asynchronous operations, especially in Flutter for building non-blocking UI applications.

• Official Documentation: Dart: Asynchronous Programming: Futures and async-await

Rust provides powerful concurrency features, including futures, through its standard library and the `futures` crate for asynchronous programming.

• Official Documentation: Rust: std::future

Scala incorporates futures and promises in its standard library, enabling effective asynchronous programming in a functional style.

• Official Documentation: Scala: Futures and Promises

Java introduced `CompletableFuture` in Java 8 as an enhancement to its concurrent programming model, which represents a future result of an asynchronous computation.

• Official Documentation: Java: CompletableFuture

Python's `asyncio` module includes support for futures, allowing for asynchronous programming patterns and non-blocking code execution.

• Official Documentation: Python: asyncio - Futures

C# uses tasks, particularly `Task` and `Task<TResult>`, as part of the Task Parallel Library (TPL) to represent asynchronous operations, which can be considered similar to futures.

• Official Documentation: Microsoft Docs: Task

While JavaScript primarily uses Promises for asynchronous operations, the concept of futures can be seen as analogous to JavaScript Promises.

• Official Documentation: MDN Web Docs: Promise

Swift provides futures and promises through third-party libraries like PromiseKit, although native support for asynchronous programming has evolved with async/await syntax.

• Third-Party Library Documentation: PromiseKit on GitHub

Kotlin does not have a built-in concept called “Future” but uses coroutines to handle asynchronous programming. Futures can be managed through third-party libraries or Kotlin's coroutine system.

• Official Documentation: Kotlin Coroutines

Go does not have an explicit “Future” type but utilizes goroutines and channels to achieve asynchronous execution and communication, which can be used to implement future-like patterns.

• Official Documentation: Go: Effective Go - Goroutines

Each of these languages has its approach to dealing with asynchronous computation, with futures or equivalent constructs providing a way to handle values that result from concurrent operations. The official documentation for each language offers comprehensive guidance on how to use these features effectively within their respective programming models.
