Have you ever struggled to pursue the intent of a specific change, or the status of the current code? The correct way to submit code can effectively avoid these difficulties. This article will dive into the best practices of software submission. Core points The correct code submission can prevent confusion and save future time.

Good submissions should be clear, insightful and atomic. The commit structure should contain types or components, clear topics, and optional body text to provide more context or details. Problems should be handled in the submission information, using keywords and question IDs

Course Introduction:Event loops are the core mechanism of JavaScript asynchronous programming. It cooperates with call stack, message queue and event loop to handle multiple tasks under a single thread. 1. The call stack executes the current task; 2. After the asynchronous operation is completed, the callback enters the message queue; 3. The event loop pushes the callback to the call stack for execution. Macro tasks (such as setTimeout) and micro tasks (such as Promise.then) have different priority: 4. After each event loop, all current micro tasks will be cleared. For example, the output order in the code is Start→End→Promise→Timeout, which means that micro-tasks take precedence over macro-task execution. In actual development, micro-tasks should be avoided indefinite recursion and do not rely on precise time control.

Course Introduction:Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
