await Task.Delay(1000); // Simulate a task taking some time return "Hello";} ``` == Kotlin - suspend Functions == Kotlin uses `suspend` functions for asynchronous programming, which can be awaited with the `await()` function when used with `Deferred` values, part of the kotlinx.coroutines library. Kotlin's coroutines provide a more structured concurrency framework compared to Python's, emphasizing flexibility and control. Kotlin documentation: s://kotlinlang.org/docs/reference/coroutines-overview.html(https://kotlinlang.org/docs/reference/coroutines-overview.html). ```kotlin suspend fun getHello(): String {
delay(1000) // Non-blocking delay for 1 second return "Hello"} ``` == JavaScript - await Operator == JavaScript supports asynchronous programming with `async` functions and the `await` operator, very similar to Python. The `await` operator is used to wait for a `Promise` to resolve, pausing the function's execution in a non-blocking manner. JavaScript's approach is widely used in web development for handling asynchronous operations like network requests. JavaScript documentation: s://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/await(https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/await). ```javascript async function getHello() {
await new Promise(resolve => setTimeout(resolve, 1000)); // Simulate a delay return "Hello";} ``` == TypeScript - await Operator == TypeScript, being a superset of JavaScript, also utilizes `async` functions and the `await` operator to handle asynchronous operations. TypeScript adds type support to these constructs, allowing for more robust development practices while maintaining the same syntax and operational behavior as JavaScript. TypeScript documentation: s://www.typescriptlang.org/docs/handbook/async-await.html(https://www.typescriptlang.org/docs/handbook/async-await.html). ```typescript async function getHello(): Promise<string> {
await new Promise(resolve => setTimeout(resolve, 1000)); // Simulate a delay return "Hello";} ``` == PHP - await Equivalent == PHP traditionally uses a synchronous execution model, but libraries like ReactPHP and Amp offer asynchronous capabilities. Unlike Python's native `await`, these libraries use promises and event loops to achieve non-blocking behavior, requiring a different programming model than the native language constructs. Amp documentation: s://amphp.org/amp/(https://amphp.org/amp/). ```php Amp\Loop::run(function () {
$promise = new Amp\Delayed(1000, "Hello"); // Delays the resolution $hello = yield $promise; echo $hello;}); ``` == Go - Goroutines and Channels == Go does not have an `await` keyword; instead, it uses goroutines and channels for concurrency. Goroutines are functions that run concurrently with other functions, while channels are used for communication between goroutines. This model is distinct from Python's coroutine-based model, emphasizing simplicity and efficiency. Go documentation: s://golang.org/doc/effective_go#goroutines(https://golang.org/doc/effective_go#goroutines). ```go func getHello(ch chan string) {
time.Sleep(1 * time.Second) ch <- "Hello"} // Usage within a main function or another goroutine ch := make(chan string) go
getHello(ch)hello := ←ch ``` == Rust - async/.await == Rust supports asynchronous programming with the `async` keyword to define asynchronous functions and `.await` for awaiting the completion of asynchronous tasks. This model is similar to Python's but is integrated into Rust's ownership and type system, offering both safety and concurrency. Rust documentation: s://rust-lang.org/learn/get-started(https://rust-lang.org/learn/get-started). ```rust async fn get_hello() → String {
tokio::time::sleep(Duration::from_secs(1)).await; "Hello".to_string()} ``` == Swift - async/await == Swift introduced `async`/`await` in version 5.5, bringing structured concurrency to the language. Similar to Python, Swift's `await` pauses the function's execution until the asynchronous operation completes, providing a clean syntax for asynchronous programming. Swift documentation: s://docs.swift.org/swift-book/LanguageGuide/Concurrency.html(https://docs.swift.org/swift-book/LanguageGuide/Concurrency.html). ```swift func getHello() async → String {
try await Task.sleep(nanoseconds: 1_000_000_000) return "Hello"} ``` == Scala - Future and Await == Scala uses `Future` and the `Await` object for handling asynchronous operations. A `Future` represents a value that may eventually become available, and the `Await` object is used to block until the future is completed. This model is more explicit about blocking compared to Python's implicit coroutine suspension. Scala documentation: s://docs.scala-lang.org/overviews/core/futures.html(https://docs.scala-lang.org/overviews/core/futures.html). ```scala val futureHello = Future {
Thread.sleep(1000) "Hello"} val hello = Await.result(futureHello, 1.second) ``` == Clojure - core.async == Clojure's approach to asynchronous programming is provided by the `core.async` library, which introduces channels for communication between concurrent processes. While it doesn't have an `await` equivalent, `core.async` offers a powerful model for non-blocking operations through the use of channel operations. Clojure documentation: s://clojure.github.io/core.async/(https://clojure.github.io/core.async/). ```clojure (go (let [hello (<! (timeout 1000
