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:
Результатом работы кода будет
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:
Результат работы программы показывает, что текущий поток создал новый поток для выполнения задачи:
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.
