Deep understanding of how the JavaScript engine executes JS code
Article Introduction:This article brings you relevant knowledge about JavaScript, which mainly introduces issues related to how the js engine executes js code. When the js engine executes js code, it will also perform lexical analysis, syntax analysis, and semantics from top to bottom. Analysis and other processing, and generate AST after the code parsing is completed. I hope it will be helpful to everyone.

How to wait for execution before nodejs closes
Article Introduction:Node.js is a very popular JavaScript runtime environment that can be used to build high-performance web applications, command line tools, web crawlers, etc. In Node.js applications, we often need to perform some operations before Node.js is closed, such as releasing resources, saving state, etc. However, before Node.js is shut down, we need to ensure that all asynchronous operations have been completed, otherwise data loss or inconsistency may result. So, how do you wait for execution before Node.js closes? This article will

How to execute PHP asynchronously without waiting for return and execute code directly
Article Introduction:PHP asynchronous execution does not wait for return. In PHP programming, sometimes you need to perform some time-consuming operations, such as making network requests, reading and writing files, etc. If traditional synchronization is used, the program will wait until the operation is completed and the result is returned. This will cause the program to be unable to do other things while waiting, thus reducing the efficiency of the program. If you use asynchronous mode, you can let the program continue to perform other tasks while waiting for the operation to complete. To put it simply, it means to directly execute other code without waiting for the return result of the operation, and then wait until the operation is completed.

Go language programming practice: execution and waiting of the main function
Article Introduction:[Title] Go language programming practice: execution and waiting of the main function. Go language is a concurrent programming language, and the execution and waiting of the main function is a very important topic. In Go, the main function is usually the main function, which is the entry point of the program and is responsible for starting the program and executing related logic. However, when it comes to concurrent programming, the way the main function executes and waits may differ. This article will explore the execution and waiting process of the main function through specific code examples. Execution of the main function In the Go language, the execution of the main function is through

AMD Zen 5 execution engine exposed: using true 512-bit FPU
Article Introduction:According to news from this website on April 5, the source Moore's LawisDead shared relevant information about the AMD Zen5 processor execution engine (ExecutionEngine) in the latest video, saying that it will use a real 512-bit floating point unit (FPU). . According to the slides shared by the source, Zen5's execution engine is described in detail, using a real 512-bit FPU. The AMD Zen4 processor uses a dual-channel 256-bit FPU when executing AVX-512 instruction workloads, while the Zen5 uses a true 512-bit FPU, which will have higher performance in processing 512-bit AVX or VNNI instructions.
