Однопоточный JavaScript и многопоточная Java: что быстрее? Асинхронное выполнение на Java и JavaScript При необходимости в JavaScript можно запускать дополнительные потоки. Но обычно в Node.js или в браузерах весь код на JavaScript выполняется в одном потоке. В браузерах один и тот же поток рендерит содержимое веб-страницы на экран. По сути, один поток выполнения занимается всеми задачами, потому что приложения JavaScript пользуются преимуществами асинхронного выполнения. Для асинхронного выполнения задача помещается в очередь задач. Задачи из очереди одна за другой выполняются единственным потоком. Например, вторая строка кода выполняет планирование асинхронной задачи, которая запускается после завершения текущей задачи: console.log("1"); setTimeout(()=>console.log("2")); console.log("3"); Результатом работы кода будет 1 3 2. В Java API под асинхронным выполнением обычно подразумевается, что задача выполняется в новом выделенном потоке. Например, представленный ниже код при помощи метода supplyAsync() планирует асинхронную задачу: System.out.println("current thread: " + Thread.currentThread().getName()); var future = CompletableFuture.supplyAsync(() -> Thread.currentThread().getName()); System.out.println("current thread: " + Thread.currentThread().getName()); System.out.println("task thread: " + future.get()); Результат работы программы показывает, что текущий поток создал новый поток для выполнения задачи: current thread: main current thread: main task thread: ForkJoinPool.commonPool-worker-1 Проблема множественных потоков заключается в том, что Java runtime не может создавать бесконечное их количество. Когда все запущенные потоки ожидают, а новые потоки создать нельзя, приложение тоже ничего не будет делать. Читать: https://habr.com/ru/post/592017/?utm_campaign=592017
