JS asynchronous programming JavaScriptOne of the major features of language is single thread, which means that all tasks need to be queued up before the last task can be executed. If the former task takes a long time, the latter one has to wait all the time. HTML5proposeWeb WorkerStandard, permissibleJavaScriptThe script creates multiple threads, but […]

History of Linux Asynchronous IO Asynchronous IO has always been a pain in Linux systems. Linux has long had the asynchronous IO implementation of POSIX AIO, but it is very inefficient to simulate user threads in user space. Later, Linux 2.6 introduced a real kernel-level support for asynchronous IO implementation (Linux aio), but it only […]

This paper illustrates the use of callback function based on nodejs asynchronous programming. Share for your reference, as follows: The direct embodiment of Node.js asynchronous programming is callback. Asynchronous programming relies on callbacks to achieve, but it can not be said that the program will be asynchronous after using callbacks. Callback functions are called when […]

For more details, click http://blog.zhangbing.club/Ja… The execution environment of Javascript language is “single thread”. If there is no asynchronous programming, it can not be used at all and must be stuck. To solve this problem, the Javascript language divides task execution patterns into two kinds: synchronous and asynchronous. Before ES6 came into being, there were […]

Recently, I read the post and found an interview question: Start two threads, one output 1,3,5,7… 99, another output 2,4,6,8… In the last STDOUT, output 1,2,3,4,5 in sequence. One hundred The title is based on Java wait + notify mechanism, focusing on the understanding of multithreading visibility. Introduction to wait and notify Wait and notify […]
