what is asynchronous programming? asynchronous programming allows tasks to be executed independently of the main program flow. this enables non-blocking operations, such as api calls or file i/o,...
异步编程允许任务独立于主程序流执行,支持非阻塞操作,如api调用和文件i/o,提升性能和用户体验。常用方法有回调、promise和async/await,适用于数据库查询和网络请求等耗时操作,确保应用快速响应。
